- Now apply the operations of all the results and simplify the whole numbers.
Evaluating Numerical Expressions Involving Whole Numbers Examples
Let us discuss the simple and easy methods to evaluate Numerical Expressions Involving Whole Numbers with examples here. So, the 5th-grade students are advised to check out the given problems and practice for the tests.
Example 1.
Simplify the numerical expression 30 + 40 ÷ 10 + 8 × 6
Solution:
Given that,
30 + 40 ÷ 10 + 8 × 6
First step: divide 40 ÷ 10
Then we get 4
Second step: multiply 8 × 6
Then we get 48
Third step: add 30 + 4 + 48 = 82
Therefore the solution of numerical expression 30 + 40 ÷ 10 + 8 × 6 = 82
Example 2.
Simplify the numerical expression 14 × 3 – 2 + 26 ÷ 3 × 4
Solution:
Given that,
14 × 3 – 2 + 26 ÷ 3 × 4
First step: multiply 14 × 3
Then we get 42
Second step: divide 26 ÷ 3
Then we get 8.6
Third step: multiply 8.6 × 4
Then we get 34.4
Fourth step: subtract 3 – 2
Then we 1
Fifth step: add 42 – 1 + 34.4 = 74.4
Therefore the solution of the numerical expression 14 × 3 – 2 + 26 ÷ 3 × 4 = 74.4
Example 3.
Simplify the numerical expression 2 × 1 + 8 + 3 × 4
Solution:
Given that
2 × 1 + 8 + 3 × 4
First step: multiply 2 × 1 = 2
Then we get 2
Second step: again multiply 3 × 4
Then we get 12
Third step: add 2 + 8 + 12 = 22
Therefore the solution of the numerical expression is 2 × 1 + 8 + 3 × 4 = 22
Example 4.
Simplify the numerical expression 12 – 4 × 2 + 8
Solution:
Given that,
12 – 4 × 2 + 8
First step: subtract 12 – 4
Then we get 8
Second step: 8× 2
Then we get 16
Third step: add 8 + 16 + 8 = 32
Therefore the solution of the numerical expression is 8 + 16 + 8 = 32
Example 5.
Simplify the numerical expression 16 × 1 – 4 + 2 × 8
Solution:
Given that,
16 × 1 – 5 + 2 × 8
First step: multiply 16 × 1
Then we get 16
Second step: subtract 16 – 1
Then we get 15
Third step: multiply 2 × 8
Then we get 16
Fourth step: add 15 + 16 = 31
Therefore the solution of the numerical expression is 16 × 1 – 5 + 2 × 8 = 31
