What is the overall change in a bank account after writing checks and making deposits?

Back

To find the overall change, subtract the total amount of checks written from the total deposits and withdrawals. For example, if you wrote two checks for $40 each, withdrew $85, and deposited $20, the overall change is calculated as follows: - (2 * 40) - 85 + 20 = -80 - 85 + 20 = -145, which means the account decreased by $145.

How do you calculate the total price change of an item over a period of time with weekly reductions?

Back

How do you determine the greatest common factor (GCF) of two numbers?

Back

To find the GCF of two numbers, list the factors of each number and identify the largest factor that appears in both lists. For example, the factors of 28 are 1, 2, 4, 7, 14, 28 and the factors of 49 are 1, 7, 49. The GCF is 7.

What are equivalent numbers?

Back

Equivalent numbers are different representations of the same value. For example, 0.5 and 1/2 are equivalent because they represent the same quantity.

Front

How do you find the total amount withdrawn from a bank account?

Back

To find the total amount withdrawn from a bank account, simply add up all the individual withdrawals. For example, if you withdrew $85, that is the total amount withdrawn.
