Order of Operations/Integers Flashcard

Front

What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does it mean to add integers?

Back

Adding integers involves combining whole numbers, which can be positive or negative. If both integers are positive, the result is positive. If both are negative, the result is negative. If one is positive and the other is negative, subtract the smaller absolute value from the larger absolute value and take the sign of the integer with the larger absolute value.

What is the significance of parentheses in mathematical expressions?

Back

Parentheses indicate which operations should be performed first in an expression, following the Order of Operations.

Front

What does it mean to multiply integers?

Back

Multiplying integers involves finding the product of whole numbers. The product of two positive integers is positive, the product of two negative integers is also positive, and the product of one positive and one negative integer is negative.
