You will decipher sentence and word based sum problems and perform the operations on these worksheets.

These worksheets help students identify situation where they are required to process an addition operation. In most cases, students need to understand what addends are and having an understanding about the concept of sums. We also get a little crazy with the math facts and are looking for more motivated learners to slap together larger sums. As we carry on, we add double sentences and more convoluted sentences that add a degree of difficulty to the problems. In math, and science for that matter, terminology is often referred to as notation and that comes up often.

Two of the addends are 10 and 13, and the sum is 39. Find the third addend. The numbers you add are addends and the answer is called sum. Addends given are 10 and 13.

## Three Different Sums Worksheet

Write 30 as sums in three different ways. We show you how and then we throw two more practice problems at you.

The problem types that you'll see are: The addends are 35, 40, 90. Find the sum. The sum is 90. The three addends are 10, 20, 44. Find the fourth addend. The sum is 500. The three addends are 190, 200, 23. Find the fourth addend. The sum of four numbers is 190. The three addends are 10, 55, 68. Find the fourth number.

## Making Sums

Write the given numbers as sums in three different ways. If you can do more, go for it!

The sum of three numbers is 100. If two of the numbers are 20, 50, then find the third number. The addends are 140 and 130. The sum is 300. Find the third addend.

Fill in the blanks. Miss your mark or don't!

## What is the Terminology Associated With Addition?

Addition is a vital part of mathematics and a concept that students should learn early on. When most people think of addition, they think of basic arithmetic: adding numbers together to get a sum. But in mathematics, addition is a much more complex concept than counting.

Addition can be used in mathematics to solve problems in geometry, algebra, and other areas of math as it can be used to add objects together, like points on a line or angles in a triangle, and also combine values, like adding two lengths to get a total length.

Properties

Some of these properties include:

The commutative property (the order of addition does not matter).

• The Closure Property (the result of adding two whole numbers will always be a whole number),
• The Associative Property (the order of addition does not matter when adding more than two numbers).
• The Additive Identity Property (adding zero to any number will not change that number).

We used some particular terminologies in addition, such as addend, Augend, and sum.

An addend is a number that is added to another number. The sum is the result of adding two or more numbers together. In other words, the answer to an additional problem. In the picture above, there are three addends: 7 + 11 + 5 = 23.
