Question : 14 of 100

Marks: +1, -0

1 4 \times 1 2 - 164 \div 18 = ?

Solution:

Concept:

Symbol substitution followed by the BODMAS rule.

Explanation:

Replace each given symbol with its defined operation.

\times \rightarrow +

\div \rightarrow -

+ \rightarrow \div

- \rightarrow \times

The expression is

14 \times 12 - 16 \div 18

After substitution, it becomes

14 + 12 \times 16 - 18

Apply BODMAS: multiplication is done before addition and subtraction.

First,

12 \times 16 = 192

Now the expression is

14 + 192 - 18

Add:

14 + 192 = 206

Subtract:

206 - 18 = 188

Answer:

188
