Question

Evaluate each expression

Answer 1

Note:

To answer this, we need to know BODMAS rule and needed to follow while solving serially.

BODMAS is an acronym that stands for Brackets, Order, Division, Multiplication, Addition, and Subtraction. It is a mnemonic device used to remember the order of operations in mathematics.

The order of operations is a set of rules that tells you which mathematical operations to perform first in a calculation. The rules are as follows:

• Brackets (or parentheses): Evaluate the expressions inside brackets first.
• Order (of operations): Evaluate exponents next.
• Division and Multiplication (from left to right): Perform division and multiplication from left to right.
• Addition and Subtraction (from left to right): Perform addition and subtraction from left to right.

For the question:

1.

4-12 ÷ 6

dividing first

4-2

now subtracting

2

therefore, answer is 2.

`\hrulefill`

2.

3 * 12 ÷ 6

dividing first

3*2

now multiplying

6

therefore, answer is 6.

`\hrulefill`

3.
`(2+4)^2`

adding number inside the box

`6^2`

6*6

now multiplying

36

therefore answer is 36.

`\hrulefill`

4.

2+5+5

7+5

12

therefore, answer is 12

`\hrulefill`

5.

4*6-6

24-6

18

therefore, answer is 18.

`\hrulefill`

6.

(11+9)÷5

20 ÷ 5

4

therefore, 4 is the answer.

`\hrulefill`

7.

6÷ 3 *5

2*5

10

therefore, answer is 10.

`\hrulefill`

8.

2+4-4

6-4

2

therefore, answer is 2.

`\hrulefill`

9.

5+5+3

10+3

13

therefore, answer is 13.

`\hrulefill`

10.

(6+4)÷5

10 ÷ 5

2

therefore, answer is 2.

`\hrulefill`

11.

6(1+5)

6 of 6

36

therefore, answer is 36.

`\hrulefill`

12.

`4+5^2`

4+5*5

4+25

29

therefore, answer is 29.
