How to substract integers?
1. First, keep the first number (known as the minuend)
2. Second, change the operation from substraction to addition
3. Third, get the opposite sign of the second number (known as the substrahend)
4. Finally, proceed with the regular addition of integers.
We are given 3 -8
The first number is 3
The second number is -8
3 + -8 = -5
In a real life situation, If you are owing your friend $8 and you have $3 to pay her.
The amount you are owing is -$8, so, when you pay her $3, you will still be owing her -$5.
