Explain the rule to solve: 5 - 9 ?
Change the -minus sign to addition and make the 9 a (-9):
5 + ( - 9 )
-3 + (-1) =
-4
9 - (-1)=
10
2 x (-4)
(-8)
8 / (-4) =
(-2)
Explain the rule to solve: 7 - ( - 8 )?
Change the - minus sign to addition and change the (-8) to an 8.
7 + 8
(-1) + 1 =
0
4 - (-4) =
8
-4 x 5 =
-20
-40 / 5 =
(-8)
