Core Conceptual Guide: Important Simplification Topics for NICL AO

Before attempting more difficult questions, understand the basic rules and practise them with small examples. Start with simple calculations involving fractions, percentages, squares, and square roots to build your confidence. Regular practice with Simplification Questions for NICL AO will help you improve calculation speed, accuracy, and time management.

1. BODMAS Rule

BODMAS tells you the order in which to solve an expression. Remember that division and multiplication have equal priority. Solve them from left to right. The same rule applies to addition and subtraction.

• B: Brackets
• O: Orders, such as powers and roots
• D: Division
• M: Multiplication
• A: Addition
• S: Subtraction

Example: Solve 20 − 12 ÷ 3 × 2.

Step 1: Divide 12 by 3.

12 ÷ 3 = 4

Step 2: Multiply by 2.

4 × 2 = 8

Step 3: Subtract from 20.

20 − 8 = 12

Answer: 12

2. Fractions and Decimals

Fractions and decimals appear in many simplification problems. Learn how to change simple fractions into decimal or percentage values.

Useful values to remember:

• 1/2 = 0.5 = 50%
• 1/4 = 0.25 = 25%
• 1/5 = 0.2 = 20%
• 1/6 ≈ 0.1667 ≈ 16.67%
• 1/8 = 0.125 = 12.5%
• 3/8 = 0.375 = 37.5%

Example: Find 3/4 of 80.

80 ÷ 4 = 20

20 × 3 = 60

Answer: 60

3. Approximation

Approximation helps you find a close answer without performing every calculation exactly. It is useful when a question asks for an approximate value.

Example: Approximate 49.7 + 20.3.

49.7 ≈ 50

20.3 ≈ 20

50 + 20 = 70

Approximate answer: 70

Tip: Round numbers carefully. The rounding method should match the question, and approximation should not be used when an exact answer is required.

4. Squares and Square Roots

The square of a number is the number multiplied by itself. The square root reverses this operation. Learn squares at least up to 30 to make calculations easier.

For example:

• 12² = 144
• 15² = 225
• √144 = 12
• √225 = 15

Example: Find √169 + 5².

√169 = 13

5² = 25

13 + 25 = 38

Answer: 38

5. Cubes and Cube Roots

A cube is a number multiplied by itself three times. A cube root gives the number that produces the stated cube.

For example:

• 3³ = 27
• 4³ = 64
• 5³ = 125
• ∛27 = 3
• ∛64 = 4
• ∛125 = 5

Example: Find ∛216 + 2³.

∛216 = 6

2³ = 8

6 + 8 = 14

Answer: 14

6. Missing Number Questions

In these questions, you need to find an unknown number represented by a letter or question mark.

Example: Find (x) if 3x + 5 = 20.

Step 1: Subtract 5 from both sides.

3x = 15

Step 2: Divide by 3.

x = 5

Answer: 5

7. Vinculum and Nested Brackets

A vinculum is a horizontal bar placed over part of an expression. When present, the expression under the bar must be evaluated first. Then continue with the remaining operations. For expressions containing brackets within brackets, solve the innermost bracket first, followed by the outer brackets.

Tip: Write each step clearly. This makes it easier to avoid missing a sign or applying an operation in the wrong order.
