Question

Whats the missing number?
–3.4 + (–8 + 2) = [ ? + (–8)] + 2

Answer 1

hint:
a+(b+c)=(a+b)+c
this is the associative property of addition

Answer 2

if you notice that property we are adding the same numbers up but just in a different order

Answer 3

like for a+(b+c)
we are adding b and c first
then we are going to add the a

but for the other side (a+b)+c
we are adding a and b first
then we are adding the c

Answer 4

example of the associative property:
(3+(-5))+7=3+(-5+7)
