(-2) + [8+3] equals (-2) + 11 which equal 9.
Given,
[(-2) +8] +3 equals ______ + 3 which equals _____ Â
(-2) + [8+3] equals (-2) + Â _____ Â which equal _____
We need to see which operation is used and fill in the blanks.
What is the associative property of addition?
It states that (a+ b) + c = a + (b + c).
We have,
[(-2) +8] +3 equals ______ + 3 which equals _____ Â
(-2) + [8+3] equals (-2) + Â _____ Â which equal _____
We can write it as:
[(-2) +8] +3 Â = 6 + 3 = 9
(-2) + [8+3] = -2 + 11 = 9
We see that,
[(-2) +8] +3 = (-2) + [8+3]
This is in the form: (a+b)+c = a+(b+c)
Thus the expression was written using the associative property of addition.
[(-2) +8] +3 equals 6 + 3 which equals 9.
(-2) + [8+3] equals (-2) + 11 which equal 9.
