Multiplying and Dividing Integers
To multiply two integers, multiply the absolute values and keep the same sign as the two integers. To divide two integers, divide the absolute values and the sign of the answer is the opposite of the dividend. Zero divided by any number is equal to 0.

multiplying and dividing integers
Multiplying Integers: multiplying two integers is a process of adding the same number multiple times. For example, 3 x 4 = 12, which is the same as 3 + 3 + 3 + 3 = 12
Dividing Integers: when dividing two integers, the result is the number of times the divisor can fit into the dividend. For example, 24 / 4 = 6, which means 4 can fit into 24 six times.
Absolute Value: the absolute value of an integer is the number without the negative sign. For example, the absolute value of -9 is 9, which is the same as 9 without the negative sign.
