"×" is a multiplication sign, the numbers before and after the multiplication sign are called factors, "=" is an equal sign, and the numbers after the equal sign are called products.

10 (factor) × (multiplication sign) 200 (factor) = (equal to sign) 2000 (product) factor is also called multiplier.

Extended data:

multiply operation

1, the same sign is positive, the different sign is negative, and the absolute value is multiplied.

Any number multiplied by zero will get zero.

3. Multiply several numbers that are not equal to zero. The sign of the product is determined by the number of negative factors. When there are odd negative factors, the product is negative, and when there are even negative factors, the product is positive.

When several numbers are multiplied, if one factor is zero, the product is zero.

5. Multiply several numbers that are not equal to zero, first determine the sign of the product, and then multiply it by the absolute value.

Division operation

1 divided by a number that is not equal to zero is equal to the reciprocal of this number.

2. Divide two numbers, the same sign is positive and the different sign is negative, and divide by the absolute value. Divide zero by any number that is not equal to zero to get zero.
