How do you find the total number of items when each person has a certain number?

Back

You multiply the number of people by the number of items each person has. For example, if 22 people each release 3 balloons, the total is 22 x 3 = 66.

Front

What is the formula to calculate the total cost of multiple items?

Back

The total cost can be calculated by multiplying the number of items by the cost per item. For example, 12 donuts at $1.50 each is calculated as 12 x $1.50.

What is perimeter?

Back

Perimeter is the total distance around a two-dimensional shape, calculated by adding the lengths of all sides.

Front

How do you calculate the perimeter of a rectangle?

Back

The perimeter of a rectangle can be calculated using the formula: P = 2(length + width). For example, for a soccer field that is 100 yards long and 80 yards wide, P = 2(100 + 80) = 360 yards.

What does PEMDAS stand for in order of operations?

Back

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). It is the order in which operations should be performed in a mathematical expression.

Solve for p: 5 + 2 x 7 - 2 = p

Back

Using PEMDAS, first multiply: 2 x 7 = 14. Then add and subtract: 5 + 14 - 2 = 17. So, p = 17.

Front

What is the equation to find the number of items per person?

Back

To find the number of items per person, you can use the equation: total items ÷ number of people = items per person.

Front

What is the relationship between multiplication and addition in finding totals?

Back

Multiplication is a faster way to add the same number multiple times. For example, 4 + 4 + 4 = 12 can be expressed as 3 x 4 = 12.
