What Is A Numeric Expression

What is Numerical Expression?

The term numerical expression is made up of two words, numerical meaning numbers, and expression significant phrase. Thus, it is a phrase involving numbers.

A numerical expression in mathematics tin can be a combination of numbers, and integers combined using mathematical operators such as addition, subtraction, multiplication, or division.

Examples of Numerical Expressions

We can course a numerical expression by combining numbers with various mathematical operators. There is no limit to the number of operators a numerical expression may contain. Some numerical expressions use but 1 operator betwixt two numbers, and some may contain more.

Some examples of numerical expression are given below:

10 + 5

250 – 75

sixty × five + x

72 ÷ viii × v – four + ane

82 + 4 – 10

Writing Numerical Expression

Any mathematical give-and-take trouble is solved by outset converting into a numerical expression. Below are some examples.

Candice has x chocolate confined. She gives iii to her sister, 1 to her friend and eats two of them. Later she visits her grandmother, and she (grandmother) offers Candice 12 more chocolate bars. How many chocolate bars does Candice have at present?

Let's look at the numbers involved in the above problem. Candice starts with 10 bars, gives away four (iii+1), eats 2 and then again gets 12 more from her grandmother. So, the numerical expression is

10 – 3 – 1 – 2 + 12

= 7 – i – two + 12

= 6 – 2 + 12

= 4 + 12

= xvi

This gives u.s.a. sixteen.
