330X24 1067X240 Calculate with an easy way How to Calculate What a Method?

The first method can be calculated in this way, the first method can be 330 times 24 as 33 times 240, and then extract the common factor to calculate, the second method is to multiply 670 times 240 as 670 times 24, and then extract the common factor to calculate.

For the specific two methods, please refer to the calculation process.

330x24+67x240

Solution: Original formula = 330x24 + 67x24x10

24x(330+670)

24x1000

Skillfully using the multiplicative distributive property can be solved, and the final answer is equal to 24000.

330x24 ten 67x240, if this question is simply calculated, the first step is to change the formula to 33 10 24 + 67 24 10, the second step is calculated as (33 + 67) 24 10, and the third step can directly calculate the answer to this question is 24000.

Method, you can multiply 330 by 24 as 33 times 240, and then extract the common factor to calculate, 2

The method is to multiply 67 by 240 as 670 times 24 and then extract the common factor to calculate.

By observing, we can see that there is a multiplier relationship between 24 and 240, so we can start with this and then convert. Method 1:

Method two.

Solution: The first type: original formula = 33 240 + 67 240

The second type: original = 330 24 + 670 24

(25x37)x40 simple calculation should first disassemble the brackets, and then combine 25 and 40 to become 25*40*37=1000*37=37000

The simple calculation method is as follows: 25x876x40=25*40*876=1000*876=876000

32x570 ten 320x44 a 320 = 32 570 + 32 440-32 10 = 32 (570 + 440-10) = 32 1000 = 32000

Dear, it can be easily calculated by using the multiplicative distributive law.

Summary. 30x277-30x347=30 (277-347)=30-70=-2100

Hello dear, I will answer for you immediately, you wait a moment [than the heart] [than the heart] [than the heart] 30x277 a 30x347 = 30 (277-347) = 30 -70 = -2100

Here are the four operations, we can do it step by step according to the four operation rules, and the final result is -2100

Solution: The original style is slippery and hidden.

35x20+(35x2)x2+35x76

35x20+35x4+35x76

35x(20+4+76)

35x100

Method: After construction, the multiplication information hall distribution law was used to realize the simple calculation of the cover tour.

35x20+70x2+35x76

35x20+35x2x2+35x76

Shishan 35 (old vertical 20 + 2x2 + 76).

35x100

The answer is 3500. Weipai.

36x44+72x28

36x44+36x2x28

36x(44+2x28)

36x(44+56)

36x100
