The commutative property of addition can be used to rarrange this to

... 0 + 18 + 34 + 26

Then the identity property of addition can be used to remove the 0 term

... 18 + 34 + 26

We can use the associative property of addition to form the sum of 34 and 26, convenient because 4 and 6 "make a 10". That sum is 60, so now the sum is

... 18 + 60

which is easily seen to be

... 78

Hey there!

Commutative property: [tex] 18 + 0 + 34 + 26 [/tex]

Identity property: [tex] 34 + 18 + 26 [/tex]

[tex] 34 + 26 = 60 [/tex]

Associative property: [tex] 60 + 18 = 78 [/tex]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[tex] 30 + 0 + 18+26 \\ 34 + 0 = 34 \\ 34 + 18 + 26 \\ 34 + 18 = 52\\ 52 + 26 = 78 \\ = 78 [/tex]

Good luck on your assignment and enjoy your day@
