How do you calculate the total cost of multiple items?

Back

To calculate the total cost, multiply the price of one item by the number of items. For example, if one keyboard costs $95 and you buy 4, the total cost is 95 x 4 = $380.

Front

What is estimation in mathematics?

Back

Estimation is a method used to find an approximate value rather than an exact answer. It helps to quickly assess if a calculated answer is reasonable.

Front

What is the formula for finding the total number of items in multiple groups?

Back

The formula is: Total = Number of items in one group x Number of groups. For example, if there are 9 plants in each row and 5 rows, Total = 9 x 5 = 45.

Front

What is the difference between exact and approximate values?

Back

Exact values are precise and accurate, while approximate values are close estimates that may not be exact.
