Write a number sentence that demonstrates each property.
commutative property of addition
associative property of addition
identity property of addition

They are usually represented like this

commutative property of addition
a+b=b+a

associative property of additon
(a+b)+c=a+(b+c)

identity property of addition
a+0=a

so number sentatnces

lets say a=1,b=2,c=3

commutative property of addition
1+2=2+1

associative property of addition
(1+2)+3=1+(2+3)

identity property of addition
1+0=1

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3
