Order of Ops/Decimals

Front

What is the order of operations in mathematics?

Back

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

What does a repeating decimal look like?

Back

A repeating decimal is a decimal fraction that eventually repeats a digit or a group of digits. For example, 0.333... (which can be written as 0.3̅) and 0.0636363... (which can be written as 0.0636̅).

Identify the first step in PEMDAS.

Back

The first step in PEMDAS is to solve expressions inside Parentheses.

What is the value of 4(3 + 2) - 5(4)?

Back

The value is 0. First, calculate inside the parentheses: 3 + 2 = 5. Then, 4 * 5 = 20 and 5 * 4 = 20. Finally, 20 - 20 = 0.

What is a decimal?

Back

A decimal is a fraction expressed in a special form. It represents a part of a whole and is written using a decimal point. For example, 0.5 represents half.

Front

What is the difference between a terminating decimal and a repeating decimal?

Back

A terminating decimal has a finite number of digits after the decimal point (e.g., 0.75), while a repeating decimal has one or more digits that repeat infinitely (e.g., 0.333...).

What is the value of 3.5 + 2.25?

Back

The value is 5.75.

Front

How do you convert a fraction to a decimal?

Back

To convert a fraction to a decimal, divide the numerator by the denominator. For example, 1/4 = 0.25.
