John wants to buy a new bike that cost $337 and he already has saved $103 estimate to find about how much more johnny’s to see if to buy the bike

estimate

340 - 100 = 240

337 -> 340

103 -> 100

340-100

= 240 left to save

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
