When I solved it the outcome was 5/6
b) - 72 - (-7)2
I got the outcome 0.
Can you help me?
My gratitude,

heheheheheh
yes it is
lol but it's inconclusive is it $\displaystyle 7^2 $ or the $\displaystyle 7\cdot 2 $ and there one part of the brain sow it as $\displaystyle 7^2 $ and while answering second part of the brain saw it as $\displaystyle 7\cdot 2 $ so that's why that typo appear
$\displaystyle -7^2 - (-7)^2 = -49 - (+49) = -98 $
$\displaystyle -7\cdot 2 - (-7)\cdot 2 = -14 - (-14) = 0 $
yeKcIm
Sorry to be pedantic but:
$\displaystyle -7^2 - (-7)^2 = -49 - (+49) = 98$?
or
$\displaystyle -7^2 - (-7)^2 = -49 - (+49) = -98$
or
$\displaystyle -7^2 - (-7)^2 = -49 - (-49) = 0$
Sorry to be a pain
