Xiao Ming is five years old this year, and he will be ten years old in five years. This is the most basic addition, five plus five equals ten.
-
Xiao Ming is five years old this year, and five years later, 5+5 equals 10, and he will be ten years old. This is a simple equation, and the calculation method can be used as a normal addition.
-
Xiao Ming is five years old. His mother was six times the age of Xiao Ming. So his mother is six years old 5=30 years old.
Mother was six years old last year 5-1=29 years old. I hope the above can be helpful to you. If you are satisfied with me, please accept.
Thank you so much.

Solution: 5 + 5 = 10, Xiao Ming is 10 years old in 5 years, and the current age + years = age in a few years.
-
Five years later it should be ten years old, simple five plus five equals ten first-grade math.
-
Xiao Ming is five years old this year, and his mother is six times older than Xiao Ming this year. 5 = 30 years old. Mom was 6 years old last year. 5-1=29 years old, I hope the above answer will help you, if you are satisfied with me, please accept. Thank you so much.

This year is 5 years old, and in 5 years it will be 5+5 is 10 years old.
-
Xiao Ming is 5 years old this year and 10 years old in 5 years.
-
5 years old this year, 1+5 next year....
After 5 years, it is 5+5=10 years old.

Fifteen years old. Rock good
It's an addition problem, and the answer is fifteen years old.
Analysis and dismantling pants: Xiao Ming was five years old before he was five years old, then he is now five years old plus five years old equals ten years old, and his age is ten years old now, and five years have passed on the basis of his current age, so adding a five years old is fifteen years old. It's a math problem, and you just have to figure out how old he is now, so he will be fifteen years old in five years, and he will be ten years old now!
The algorithm for this math problem is 5+5+5=15.
In the actual process of solving the problem, it is often seen that the two "fives" in the question directly become ten years old (i.e., five plus five), but this way of solving is wrong and does not carry out in-depth thinking.
How to calculate age:
The customary method of calculating age in China is based on the calendar year experienced after birth, that is, it is counted as one year old at birth, and one year is added for each subsequent New Year. Generally, it is calculated according to the Lunar New Year, and some are calculated according to the Gregorian calendar.
For example, a baby born at the end of December is counted as 1 year old after birth, and 1 year old after January 1 of the Gregorian calendar or the local Lunar New Year, so that the baby is only a few days old and is already 2 years old. This method of calculating imaginary years is simple to calculate, but it is not scientific.

Five years ago to five years later is equal to eleven years old, this year is one year old, plus five years ago and five years later, a total of ten years, that is, eleven years old.
Let's continue to explain to you about the "age difference problem", which is a more error-prone type of question in the second grade, let's take a look!
First of all, let's take a look at the first type of question in "Age Difference Problem" Sakura.
Example 1: Xiao Ming is 6 years old this year, Xiao Qiang is 4 years old this year, 2 years later, how old is Xiao Ming than Xiao Qiang?
Analysis: When encountering this kind of problem, we must first look at the question in the question, "How old is Xiao Ming stronger than Xiao Ming in 2 years?" "Then we have to figure out how different they are this year.
Calculate their age difference this year: 6-4=2 (years) That is, Xiao Ming is two years stronger than Xiao Ming this year. So, at this time, we need to think, how old will they be in 2 years?
Xiao Ming's age after two years: 6+2=8 (years).
Xiaoqiang's age after two years: 4+2=6 (years).
Their age difference after two years was: 8-6=2 (years).
So, the age difference between them after two years is also two years. At this time, all our students should pay attention! One of the most important knowledge points in the issue of age is that "whether it is a few years ago or a few years later, the age difference will never change".
Example 2: Grandpa Bi is 65 years old this year, Xiao Ming is 8 years old this year, 5 years later, how old is grandpa than Xiao Ming?
Analysis: Since we have mastered the knowledge point that "whether it is a few years ago or a few years later, the age difference will never change", so the age difference between grandpa and Xiao Ming will be the same after 5 years. Then we can directly calculate the age difference between the two this year.
65-8=57 (years old) shows that the age difference between the two is 57 years old, and the age of both of them has increased after 5 years, but the age difference remains the same, so after 5 years, grandpa is still 57 years older than Xiao Ming.
Isn't it very easy to start the questions after mastering the knowledge points? Okay, let's take a look at the second type of question in the "age difference problem".
Example 1: Xiaohua and his brother are 16 years old this year, and the elder brother is 2 years older than the younger brother.
Analysis: Although they are all "age problems", we can't continue to use the methods used in solving the above problems when encountering this type of question, we must pay attention to the "the sum of the ages of the two is 16, and the age difference is 2". Therefore, the ages of Xiaohua and his brother this year are:
Brother = (16 + 2) 2 = 9 (years old).
Xiaohua = (16-2) 2 = 7 (years).
Then, 5 years later, the ages of Xiaohua and his brother are:
Brother = 9 + 5 = 14 (years old).
Xiaohua = 7 + 5 = 12 (years old).

Summary. If Xiao Ming is 2 years old before he is 5 years old, then his current age should be 5 - 5-2) = 2 + 3 = 5 years old. If you want to know Xiao Ming's age in 5 years, you only need to add 5 to his current age, that is, 5+5=10 years old.
So Xiao Ming will be 10 years old in 5 years.
Xiao Ming was 2 years old before he was 5 years old, so how old was Xiao Ming 5 years later.
Hello, I'm very sorry to keep you waiting, according to the problem you described: Xiao Ming was 2 years old before he was 5 years old, and how old was Xiao Ming after 5 years.
If Xiao Ming is now 5 years old and has been 2 years old before selling skating, then his current age should be 5 - 5-2) =2 + 3 = 5 years old. If you want to know Xiao Ming's age in 5 years, only Lingla needs to add 5 to his current age, that is, 5+5=10 years old. So Xiao Ming will be 10 years old in 5 years.
What I don't understand is why I'm 10 years old.
There is a mistake. If Xiao Ming is 2 years old before he is 5 years old, then his current age should be 5 - 2 = 3 years old. If you want to know Xiao Ming's age in 5 years, you only need to add 5 to his current age, that is, 3+5=8 years old.
So Xiao Ming will be 8 years old in 5 years. Thank you very much for pointing out my mistakes.
This year is 2022. By 2029 is seven years later. If you are 13 years old this year, then by 2029 If you are 13 years old this year, then you will be 20 years old by 2029.
Hello, four years later, Xiao Ming is three years older than Xiao Gang, it can be considered that Xiao Ming is three years older than Xiao Gang every year, then four years later, Xiao Ming Xiao Gang is 25 + 4 2 = 33 years old.
