# Numerical Expression For Preschoolers – Definition And Solved Problems

It is not easy for children to understand the concept of numerical expressions easily. Therefore, it is very important to teach this to them in an easy way. In this article, we will learn the definition of a numerical expression, writing numerical expressions, and how to solve numerical expressions. We have discussed below the examples for children to clearly understand this important mathematical concept.

For children writing and interpreting these numerical expressions is important because when reading real- word problems, it involves setting up the expression’s that children can clearly understand and know what keywords to look for when looking at an expression to solve it.

Let’s get started and teach our little ones about numerical expressions in mathematics.

## What Is Numerical Expression?

Let’s understand the meaning of the term with the help of a numerical expression definition.

The numerical expression consists of two words – “numerical”, meaning numbers and “expression”, meaning phrase. Therefore, numerical expressions involve numbers. It is basically a combination of numbers and integers that are combined using mathematical operations such as addition, subtraction, multiplication, and division.

## Examples Of Numerical Expression

To make it easy to understand the meaning of the numerical expression, here are some examples for children.

• 47 + 5
• 100 – 75
• 56 x 4 – 6
• 23 x 5 + 2
• 60 / 3 x 7 – 2 + 1

## Word Problems On Numerical Expression For Preschooler

Here are some numerical expression problems for preschoolers to solve and practise. These problems involve the use of addition and subtraction to solve the problem. With the help of these problems, your child will be able to enhance their problem-solving skills, which will help them later in their academic life.

Word problems in maths involve first converting them into a numerical expression. Therefore, teach your child to read the word problem first and then visualise what it is saying. Then note down the numbers given in the questions and, one by one, solve each operation. Look at the examples of numerical expression below to understand them in a better way:

Example 1: Evaluate the numerical expression: 20 + 15 – 8.

Solution:

Step 1: 20 + 15 – 8 [Given]
Step 2: = 35 – 8
Step 3: = 27
Step 4: So, 20 + 15 – 8 = 27.

Example 2: Nandini has 7 white chocolate bars. She gives 3 white chocolates to her sister, 1 to her niece and eats 2. Later Nandini visits her grandmother, and she (grandmother) offers Nandini 10 more chocolate bars. How many chocolate bars does Nandini have now?

Solution:

Let us first look at the numbers involved in the problem above. Nandini has 7 white chocolate bars. She gives away 4 white chocolates (3 to her sister and 1 to her niece), eats 2 and then again gets 10 more chocolate from her grandmother.
Thus, it can be represented in numerical expression as 7 – 3 – 1 – 2 + 10
= 4 – 1 – 2 + 10
= 3 – 2 + 10
= 1 + 10
= 11
Hence, Nandini now has 11 chocolate bars.

Example 3: Suraj is a farmer with 10 watermelons from his farm to give to his neighbours. He gives 5 watermelons to Rohan and 3 to Mohan in the morning. In the evening, Gaurav, another farmer in that village, gifts 3 watermelons to Suraj. At the end of the day, how many watermelons does Suraj have?

Solution:

Let’s first note down all the numbers we can find in the question above.
At first, Suraj had 10 watermelons. He gave 8 watermelons in the morning
(5 to Rohan and 3 to Mohan).
In the evening, Gaurav gave 3 watermelons to Suraj.
Therefore, the numerical expression for this problem is:
= 10 – 5 – 3 + 3
= 5 – 3 + 3
= 2 + 3
= 5
Therefore, Suraj has 5 watermelons left with him at the end of the day. Writer, journalist and content creator, she has worked across several publications.
