Q

Order of operations

A

In mathematics and computer programming, the order of operations (or operator precedence) is a collection of rules that define which procedures to perform first in order to evaluate a given mathematical expression.

2
Q

Function

A

a relationship or expression involving one or more variables.

3
Q

Ordered pair

A

An ordered pair is a pair of numbers used to locate a point on a coordinate plane; the first number tells how far to move horizontally and the second number tells how far to move vertically.

4
Q

Coordinates

A

It is formed by a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.

5
Q

Scientific notation

A

Or it might be a small number, like 0.0000073. Scientific notation is a way to make these numbers easier to work with.

6
Q

Numerator

A

In mathematics, the number that appears on the top of a fraction. In the fraction 2/3, the numerator is 2.

7
Q

Denominators

A

The denominator is the bottom part of a fraction. For example, in the fraction 3/4, the denominator is 4.

8
Q

Reciprocal

A

Every number has a reciprocal except 0 (1/0 is undefined) The reciprocal is shown as 1/x, or x-1. When we multiply a number by its reciprocal we get 1.

9
Q

Mean

A

The “mean” is the “average” you’re used to, where you add up all the numbers and then divide by the number of numbers.

10
Q

Median

A

The “mean” is the “average” you’re used to, where you add up all the numbers and then divide by the number of numbers.

11
Q

Mode

A

To find the median, your numbers have to be listed in numerical order, so you may have to rewrite your list first. The “mode” is the value that occurs most often.

12
Q

Range

A

To find the median, your numbers have to be listed in numerical order, so you may have to rewrite your list first. The “mode” is the value that occurs most often.
