Simplification using BODMAS
BODMAS stands for

Brackets (parts of a calculation inside brackets always come first).

Orders (numbers involving powers or square roots).

Division.

Multiplication.

Addition.

Subtraction.
How to Apply BODMAS?
first simplify the brackets from the inside to the outside ( ), then evaluate the exponents or roots, simplify multiplication and division, and finally perform addition and subtraction operations while moving from left to right.

Que1: 24 – 20 ÷ 5 x 2
Solution According to BODMAS first, we do the division then multiplication then subtraction.
24 – 20 ÷ 5 × 2
= 24 – 4 × 2
= 24 – 8 = 16 Ans.
Que2: 19 + 12 ÷ 6 – 2 x 3
Solution According to BODMAS first, we do the division then multiplication then addition then subtraction,
19 + 12 ÷ 6 – 2 × 3
= 19 + 2 – 2 × 3
= 19 + 2 – 6
⇒ 21 – 6 = 15 Ans.
Que3: 21 – 12 ÷ 4 – 3 x (7)
Solution 21 – 3 – 3 x (7)
= 21 – 3 + 21
= 21 + 18 = 39 Ans.
Que4: 23 + 18 ÷ 6 + 3 x (4)
Solution 23 + 3 + 3 x (4)
= 23 + 3 – 12
= 26 – 12 = 14 Ans.
Que5: 30 – {8 ÷ (2 x 3 – 4)}
Solution 30 – {8 ÷ (6 – 4)}
= 30 – {8 ÷ 2}
= 30 – 4 = 26 Ans.
Que6: 9 – {5 x 3 + 12 x 16 ÷ (8)}
Solution 9 – {5 x 3 + 12 x (2)}
= 9 – {15 – 24}
= 9 – (9) = 18 Ans.
Que7: 16 – {9 – 24 ÷ (8 + 6 x 2 – 16)}
Solution 16 – {9 – 24 ÷ (8 + 12 – 16)}
= 16 – {9 – 24 ÷ 4}
= 16 – {9 – 6}
⇒ 16 – 3 = 13 Ans.
Que8: 12 – [13 – {9 + 10 ÷ (7 – 2)}]
Solution 12 – [13 – {9 + 10 ÷ 5}]
= 12 – [13 – {9 + 2}]
= 12 – [13 – 11]
⇒ 12 – 2 = 10 Ans.
Que9: 4 – [16 – {6 + 12 ÷ (9 – 6)}]
Solution 4 – [16 – {6 + 12 ÷ 3}]
= 4 – [16 – {6 + 4}]
= 4 – [16 – 10]
⇒ 4 – 6 = 2 Ans.
Que10: 28 – [15 – {8 + 20 ÷ (7 – 8 – 6)}]
Solution 28 – [15 – {8 + 20 ÷ (7 – 2)}]
= 28 – [15 – {8 + 20 ÷ 5}]
= 28 – [15 – {8 + 4}]
⇒ 28 – [15 – 12]
⇒ 28 – 3 = 25 Ans.
