A primary 1 math problem to find the answer

Take the "six" in the ten place as "nine", and the "three" in the unit position as "five", that is, take 63 as 95, and calculate 97, so 95-(-2) = 97, so 63-(-2) = 65, and finally 65

Topic. Xiao Confused does a subtraction math problem, the 6 in the ten digit is 9, the 3 in the single digit is 5, and the subtracted number is 97 in the end, what is the correct answer?

Answer. Ten is the upper count: 9-6=3

is the upper multiple: 5-3=2

So find out: (9-3)x10+(7-2)x1=65

If you take the 6 in the 10th place as 9, you must have seen 30 more, and if you look at the 3 in the single digit as 5, you must have seen 2 more 97-30=67 67-2=65

This man is blind, isn't he? You can treat 6 as 9 and 3 as 5

Total = 65

If you take 6 as 9 in the 10th place, you will have 30 more, so you have to subtract 30, 97-30 = 67

Take the 3 in the single digit as 5, so there is more than 2, to subtract, 67-2 = 65

It is to take 63 as 95, so the answer is 32 more than the correct answer, so the wrong answer 97-32=65 is the correct answer.

A x = 158 17

Hello classmate Minmo, if the problem has been solved, remember to be cautious in the upper right corner Your bridge Xiaodou is an affirmation of me Thank you.

I've just seen this topic, maybe it's your child's classmate.

The second person buys more than half of the remaining eggs, and if there is one egg left in the basket, half of the remaining eggs is 1+1=2.

Then the remaining eggs are 2*2=4

The first person buys more than half of the eggs in the basket, and if there are 4 eggs left, half of the eggs in the basket is 1+4=5.

So there are a total of 5*2=10 eggs in the basket.

Suppose Mrs. Wang has a total of x eggs, the total number of eggs.

The number of eggs sold for the first time The number of eggs sold for the second time The number of eggs left x (1 2x+1)+1 2[x-(1 2x+1)]+1+1, the equation is left and right at the same time 4 4x=2x+2+2+2x-x-2+4+4 Find: x=8 The number of eggs sold The number of eggs in the original total minus the number of eggs remaining 8-1=7 Mrs. Wang sold a total of 7 eggs.

Ten eggs, the first person bought 6, the second person bought 3, and finally there was one left.

Grandma Wang sold a total of 9 eggs.

I'll write it down to you right away

The little bees are very industrious and constantly pull out of the hive.

The card, marked with 2, pulls out the result of the calculation card is 2, and the one that has been pulled out is 7-5=2

There are also 1+1=2 3-1=2 4-2=2 5-3=2 6-4=2 8-6=2 9-7=2

The one identified as 3 already has 6-3=3, so what else? 1+2=3 2+1=3 4-1=3 5-2=3。。。

This is an enlightening method of education, and when the child understands it, he will make progress!

Don't think of it as a problem, it should be seen as a game, and the child will be interested and will use his brain.

The estimator is the card.

The question asks which equations 2, 3, 4, 5, 6, and 7 can be calculated.

The questions should test the understanding and application of addition and subtraction (within ten).

The person who made the question is just a problem, and the question is not clear.

I don't know how to answer or how to think.

Such a question can easily trap a child's thinking ability.

3 squares are 1, circles are 2, triangles are 5

1 block outside 1+2=3

2 circles outside 2-1=1

3 blocks outside 1+5=6

4 triangles are outside 5-1=4

5 triangles are outside 5-2=3

Is this 1st grade math?

That's pretty hard! Admire the brothers above.
