I think you will agree with me when I say some students find it challenging when multiplying and dividing an integer by another integer.
But it needn’t be if you know what they are and how to carry out their multiplication and division efficiently.
What is an integer and how do we multiply and divide them?
Integers are negative and positive numbers, including zero.
….., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, …..
Here are some key points to remember when multiplying integers.
- Multiplying two integers of the same signs gives a positive answer.
- Multiplying two integers of different signs gives a negative answer.
Example (1) 4 x 3 = 12 (4 and 3 are both positive integers)
