375x16 Easy Calculation? 74x63 74 63 easy calculation?

This simple method calculation problem uses the method of splitting numbers, and then uses the method of multiplication and associativity to perform simple calculations, we first split 375 into 400-25, and then we get the equation (400-25) 16 (why don't I split 16?). Because even if the number obtained by dividing 16 is multiplied by 375, it is still relatively large and difficult to calculate, for example, 375 (20-4) = 375 20-375 4, so it is more troublesome to calculate), now in the division according to the multiplicative distributive law, we get 400 16-25 16, and now we are calculating according to the order of the mixed operations around the week, 400 16 = 6400, 25 16 = 25 4 4 = 400, 6400-400 = 6000. The use of the law of operation can make the calculation easier, I hope mine can help you, I wish you progress in your studies, thank you!

To do the simple calculation, then first turn three hundred and seventy-five into twenty-five times fifteen. Then turn sixteen into four times four. Then calculate that twenty-five times four equals one hundred, and fifteen times four equals sixty. Sixty multiplied by one hundred equals six thousand.

When using simple calculations, first decompose the original numbers, and use the associative law of multiplication to multiply the two numbers to become one hundred, so that the calculation will be particularly simple. The formula for the associative law of multiplication is a multiplied by b multiplied by c, which is equal to a multiplied by parentheses and b multiplied by c. In addition, the rounding method is used, where two numbers are multiplied, added or subtracted.

Equal to a hundred or a thousand.

When calculating, if you can use simple methods, it is better to use simple methods, in addition, this is to have the mastery of the number series, various operation laws and properties, only in this way can you make small errors in the calculation, and can save time.

This can be easily calculated.

The common factor 65 is extracted, and the original formula is equal to 65 (37+45) 65 82 4910.

Just look at the math textbooks about simple calculations.

74x63-74 63 Extract the total term 74 first, easy to calculate.

74 63-74 63 is easy to calculate, this does not need to be calculated on several sides, this is the same two numbers multiplied, and then subtracted is equal to zero, because ah is to calculate multiplication and division first and then add and subtract, so you need to calculate 74 times 63 and 74 times 63, and then subtract them, so you don't need to carry out inheritance, directly subtract the city, that is, 00

Here's how to calculate it, I hope it can help you. There are two ways to do this:

The first approach is:

74x63-74×63

The second approach is:

Of course, there is a third algorithm, which is calculated directly, and this problem can be seen at a glance to be equal to 0.

No need to calculate, just equal to 0. Since the multiplier of the two multiplications is the same, the product of the two multiplications is also the same, and then subtract the two products, and the result must be 0.

The sum of two opposite numbers is 0.

A simple calculation of equation 74 63-74 63 is carried out, and the results are as follows:

Simple calculation as.

Or just write.

It is estimated that everyone knows that the product of two identical numbers must be the same, so it is okay to write equal to 0 directly.

The simple calculation of this formula is: the original formula 63 (74-74) 63 0 0.

74x63-74x63 simple operation.

74x（63-63）74x0

In fact, you don't need to do simple calculations, you can get 0 directly, and the subtraction of two identical equations must be equal to 0

74x63 74 63 easy calculation?

In your question, since the subtracted and subtracted numbers are equal, the difference between them is 0

This means that any equal 2 numbers or polynomial subtraction results are oh, so:

The multiplier and the multiplier are the same, and the equation is obtained

Multiplying zero by any number gives us zero.

The simple calculation is as follows, the original formula = 74 (63-63) = 74 0 = 0

There are two ways to do this question: first: 74*63-74*63 74*(63-63) 74*0 0

Second: 74*63-74*63 63*(74-74) 63*0 0

This can be put up with shredded bamboo shoots or 63 first, and then it is indeed multiplied by 63-3 or 63 74-4, in this case, what is his final answer is. It's zero.

This question does not have to be a simple calculation. Because the subtraction and the subtraction are exactly equal, it is easiest to calculate directly. As follows: 74 63-74 63 0

This does not need to be easily calculated, and it can be concluded that the subtraction and the subtraction are equal, and the obtained number is equal to 0.

Hello this question can be done like this: (74 74) 63=0

Is this still easy to calculate? The difference between the subtraction of two numbers with the same side of the minus sign is zero.

The simple algorithm is as follows, the above equation = 74 (63-63)=0

The subtraction of the same numbers is equal to zero, so the solution can look like this:

74-74）x（36-36）

This can be regarded as 74 63 as a whole, expressed by 1, it is simple, 1-1 = 0. So 74 63-74 63 = 0

Since both multiplication equations have 73, the inverse of the distributive law using multiplication has 73 (146-46) = 7300

It is possible to extract the common factor calculation, 146 73-73 46 73 (146-46) 73-100 7300

Apply the distributive branch. Mammoth Mountain.
