"m" is an unknown variable/alphabet, whose value you need to find out
m+8= -12
m= -12 - 8
m= -20
40
first add 12 plus 12 equals 24, then add 4 plus 4 and that equals 8. 24 plus 8 equals 32. 12 + 12 = 24 4 +4 =8 24 + 8 =32
-12
I'll do ya one better - 12 plus 8 equals what?
12
4 + 8 = 12 is correct.
12 of course !
12
46
4
5 + -8 = 3 + 12 -3 is not equal to 15
Addition is commutative. That is, a + b = b + a for all a, b
