Question

$120 \div (18 - {20 - 3(9 - 5)})$
​

Answer 1

QUESTION :

$120 \div (18 - {20 - 3(9 - 5)})$

SOLUTION :

$⟹120 \div (18 - {20 - 3(9 - 5)})$

we have to solve this question using BODMAS :-

So first we will solve the part which is inside bracket :-

$⟹120 \div (18 - {20 - 3(4)})$

$⟹120 \div (18 - {20 - 12})$

$⟹120 \div (18 - 32)$

$⟹120 \div (- 14)$

$⟹120 \times \frac{1}{( - 14)}$

( cancel 120 and 14 by 2)

$⟹ - \frac{60}{7}$

ANSWER :

$- \frac{60}{7}$

BODMAS is used to simplify the expressions having different operators (+,-,÷or ×) . It is basically a specific order.

B => Brackets

O => Orders or Of

D => Division

M => Multiplication

A => Addition

S => Subtraction

This means start solving first anything which is inside bracket. Then evaluate any root or power. Then do division , multiplication , addition and subtraction in the sequence of BODMAS.
