Question

Lennon has a checing account. He withdrew $130 from the ATM Tuesday. Wednesday he deposited $240. Friday he wrote a check for $56. What was the the total change in Lennon's account

Answer 1

The answer is 54. You take -130 and add it to 240 then you subtract 56. 

Answer 2

$166 is the answer because
if he withdrew $130 it means he is now at -130
He added $240 now he has $110 since -$130 + $240 = $110
he added another $56 now
110 + 56 = 166
