Understanding Order of Operations: PEMDAS/BODMAS
When you see a math problem with multiple operations, it's important to solve it in the correct order. PEMDAS (or BODMAS) helps remember this order:
- Parentheses (or Brackets)
- Exponents (or Orders/Indices)
- Multiplication and Division (left to right)
- Addition and Subtraction (left to right)
Understanding LCM and HCF
Highest Common Factor (HCF / GCD): The largest positive integer that divides each of the integers without a remainder. Example: $HCF(12, 18) = 6$.
Least Common Multiple (LCM): The smallest positive integer that is a multiple of all the integers. Example: $LCM(4, 6) = 12$. It can be found using $ LCM(a, b) = \frac{|a \times b|}{HCF(a, b)} $.

Understanding HTU (Column Method)
The HTU (Hundreds, Tens, Units) method, or column method, visually organizes numbers for basic operations, emphasizing place value and regrouping (carrying/borrowing).
- Addition: Align numbers by place value. Add columns from right, carrying sums $\ge 10$.
- Subtraction: Align numbers. Subtract columns from right, borrowing if a top digit is smaller.
- Multiplication (Long): Multiply by each digit of the multiplier, creating shifted partial products. Sum these products.
