Question

Orally IWUMCYUSU JIUV,
a-b= a + additive inverse of b = a + (-5)
a - (- b) = a + additive inverse of (- b) = a + b
(-10) + 3 = -7 and 10 - 3 = 7
(-10) + 3 + 10 - 3
8 + (-7) -(-4) = 8 +(-7) + 4 = 1 + 4 = 5
8 + 7 -4 = 15 -4 = 11
8 + (-7) - (-4) = 8 - 7 + 4
-+-​

Answer 1

answer

step by step

IWUMCYUSU JIUV

so

8-7+4

=8-7+4

=8-3

=5
