Too much or too much, it is generally a language problem. Mathematically, as long as it is more than twice, you can say more.

Compared with the smaller quantity, the two quantities are similar, so we say more. If the smaller quantity is much larger, say much more.

take for example

Such as 8 and 1, 8 and 7.

8- 1=7

8-7= 1

Obviously, the number 7 is relatively large, and 1 is relatively small.

So 8 is much more than 1, and 8 is only a little more than 7.

More and more have different mathematical meanings:

Multiplication is a simple operation of addition and division is a simple operation of subtraction.

Subtraction and addition are reciprocal operations, and division and multiplication are reciprocal operations.

Integer addition and subtraction algorithm;

(1) Same-digit alignment;

(2) from the unit;

(3) When it is added to dozens, it will be pushed to a higher position; If the subtraction is not enough, subtract 1 from the high position. When this number is added to 10, it will decrease.

Properties of addition operation

From additive commutative law's associative law, it can be concluded that when several addends are added, the positions of addends can be exchanged at will; Or add a few addends first and then add them with other addends, and the sum remains the same. For example: 34+72+66+28 = (34+66)+(72+28) = 200.
