Q. A bank records deposits as positive numbers and withdrawals as negative numbers. Mike withdrew

60

from his bank account

3

times. What is the change in Mike's account balance after all withdrawals?

Understand the problem: Understand the problem. $\newline$ Mike withdrew $\$60$ from his bank account $3$ times. Each withdrawal is a negative impact on his account balance.
Multiply withdrawals: Multiply the withdrawal amount by the number of times he withdrew money. $\$60$ withdrawal each time $\times 3$ times = $\$180$ total withdrawal.
Represent total withdrawal: Since withdrawals are recorded as negative, we represent the total withdrawal as a negative number. $\newline$ Total change in account balance = $-\$180$ .
