-8 -2= -10. Florin is owing 8 dollars and he is also owing 2 dollars, how much is the owing altogether? 10 dollars. – 8 – 2= -10.
Let’s move to the addition
5 + 5= 10
6 + 2 =8
- 5 + 8 = 3
You have 8 dollars and you owe 5 dollars when you pay the 5 dollars you owe, you will have 3 dollars to yourself.
Try these out - 4 – 6 =
- 2 – 5 =
- 6 + 3 =
- 5 + 9 =
-1 + 8 =
