Frequently Asked Questions about Addition Keywords

What are keywords for addition in math?
Addition keywords are signal words that tell you to add. Common examples include: sum, plus, total, increased by, more than, altogether, combined, in all, added to, gain, deposit, grow, extend, collect, put together, and earn.
What does increased by mean in math?
Increased by means a value has been made larger by a specific amount. You add the two numbers. For example, 10 increased by 4 means 10 + 4 = 14.
Is total always an addition keyword?
Usually yes. Total asks you to combine all values. However, in multiplication total can also appear (e.g., the total in 4 groups of 5). Look at surrounding words to confirm the operation.
What is the difference between sum and total?
Sum refers specifically to the result of addition (the sum of 4 and 6 is 10). Total is a broader term meaning the complete amount, often used after adding multiple values. Both signal addition.
How do I know if more than means addition or comparison?
More than signals addition when you are finding a new amount (she has 5 more than him — how many does she have?). If you are asked to compare two amounts or find the gap, it may involve subtraction instead.
What is the result of an addition problem called?
The result of an addition problem is called the sum. The numbers being added are called addends. In 6 + 9 = 15, the numbers 6 and 9 are addends and 15 is the sum.
Does gain always mean addition in math?
Yes — gain signals addition because it means receiving or earning more. A player gained 20 points means add 20 to their existing score.
What does deposit mean in a math word problem?
Deposit appears in money problems and means adding an amount to an existing balance. An account with $500 that receives a $200 deposit has a new balance of 500 + 200 = $700.
Are perimeter problems addition problems?
Yes — finding the perimeter of a shape requires adding all the side lengths. A rectangle with sides 5 cm and 3 cm has perimeter = 5 + 3 + 5 + 3 = 16 cm.
What does accumulate mean in a math problem?
Accumulate means to build up a total gradually over time by repeatedly adding. For example, saving $50 per week accumulates to $200 after 4 weeks.
