What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times (3 + 3 + 3 + 3 = 12).

How do you calculate the total number of items produced over several days?

Back

To find the total number of items produced over several days, multiply the number of items produced each day by the number of days. For example, if a company makes 625 cell phone cases each day for 31 days, the total is 625 x 31 = 19,375.

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane. The first number represents the x-coordinate (horizontal position), and the second number represents the y-coordinate (vertical position).

What does the x-coordinate indicate in an ordered pair?

Back

The x-coordinate indicates the horizontal position of a point on the coordinate plane. For example, in the ordered pair (3, 0), the x-coordinate is 3, meaning the point is 3 units to the right of the origin (0,0).

What is the order of operations in math?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often remembered by the acronym PEMDAS.

How do you solve an expression with parentheses?

Back

To solve an expression with parentheses, first perform the operations inside the parentheses. For example, in the expression [45 - (6 + 3)] × 27, first calculate (6 + 3) = 9, then substitute back into the expression.

What is a graph?

Back

A graph is a visual representation of data or mathematical relationships. It shows how two variables are related, typically using a coordinate plane with an x-axis (horizontal) and a y-axis (vertical).

What is a shape with right angles called?

Back

A shape with right angles (90 degrees) is called a right angle shape. Common examples include squares and rectangles.

What is the difference between acute, obtuse, and right angles?

Back

An acute angle is less than 90 degrees, a right angle is exactly 90 degrees, and an obtuse angle is greater than 90 degrees but less than 180 degrees.
