Answer:
(1+10)+18=11+18=29; 1+(10+18)=1+28=29
Step-by-step explanation:
the associative property of addition means that no matter in what order you group the numbers for addition the results come out to be the same.
using the associative property of addition to find the total of 1,10, and 18 in two different ways
first: (1+10)+18
=11+18
=29
second: 1+(10+18)
=1+28
=29!
