Find the digit in the decimal place you're rounding to, look at the digit one place to the right — if it's 5 or more, round up; if 4 or less, leave it and remove everything after.
Questions
- How do you add and subtract negative numbers?
- What happens when you subtract a negative number?

Questions
- How do you add fractions?
- How do you add fractions with different denominators?
- What must you do before adding fractions?
- How do you add ¾ + ⅔?
Key words
Say it
Make the denominators the same by finding a common multiple, convert both fractions, then add the numerators — the denominator stays the same.
Questions
- How do you multiply fractions?
- What's the method for multiplying two fractions?
- Do you need a common denominator to multiply fractions?
- How do you multiply ⅔ × ¾?
Key words
Say it
Multiply top by top and bottom by bottom — no need to find common denominators. Simplify at the end, or cancel before you start.
Questions
- How do you divide fractions?
- What is keep-change-flip?
- How do you divide one fraction by another?
- How do you divide ¾ by ½?
Key words
Say it
Keep the first fraction, Change ÷ to ×, Flip the second fraction — then multiply as normal.
Questions
- How do you convert a mixed number to an improper fraction?
- How do you turn an improper fraction into a mixed number?
- What is a mixed number?
- What is an improper fraction?
Key words
Say it
Mixed to improper: multiply whole number by denominator and add the numerator. Improper to mixed: divide numerator by denominator, remainder goes on top.
Questions
- How do you convert between fractions, decimals and percentages?
- How do you turn a fraction into a percentage?
- How do you turn a decimal into a fraction?
- How do you convert 0.35 to a percentage?
Key words
Say it
Fraction to decimal: divide top by bottom. Decimal to percentage: multiply by 100. Percentage to fraction: write over 100 and simplify.
Questions
- How do you find a percentage of an amount?
- How do you calculate 35% of 240?
- What's the method for finding a percentage of a quantity?
- How do I work out 17.5% of 80?
Key words
Say it
Change the percentage to a decimal by dividing by 100, then multiply by the amount.
Questions
- How do you increase an amount by a percentage?
- How do you decrease an amount by a percentage?
- What is the multiplier method?
- How do you work out a 15% increase?
Key words
Say it
Find the percentage amount and add or subtract it from the original. Or use a multiplier: increase by 20% means × 1.20, decrease by 20% means × 0.80.
Questions
- How do you solve a one-step equation?
- How do you find x when x + 5 = 12?
- What does it mean to solve an equation?
- How do you isolate the unknown?
Key words
Say it
Whatever operation is applied to x, do the opposite to both sides — keep the equation balanced at all times.
Questions
- How do you solve a two-step equation?
- How do you solve 2x + 3 = 11?
- What order do you undo operations when solving equations?
- How do you solve equations with two steps?
Key words
Say it
Undo the operations in reverse order — deal with the add or subtract first, then the multiply or divide.
Questions
- How do you expand brackets?
- What does expanding brackets mean?
- How do you multiply out 3(x + 4)?
- How do you expand a single bracket?
Key words
Say it
Multiply everything inside the brackets by the term outside — every single term inside gets multiplied.
Questions
- How do you find the nth term of a linear sequence?
- What is the nth term formula?
- How do you describe an arithmetic sequence algebraically?
- How do you find the rule for 3, 7, 11, 15...?

Questions
- How do you find the area of a rectangle?
- What is the formula for area of a rectangle?
- How do you calculate area?
- What units do you use for area?
Key words
Say it
Area of a rectangle = length × width. Make sure both measurements are in the same units, and always write the answer in square units.
Example
Rectangle 8cm × 5cm (Area = length × width) → Area = 8 × 5 = 40 cm² (Units must be squared)
Questions
- How do you find the area of a triangle?
- What is the formula for the area of a triangle?
- Why do you halve when finding the area of a triangle?
- What is the perpendicular height?
Key words
Say it
Area of a triangle = ½ × base × perpendicular height. The height must be the straight-up distance, not the slanted side.
Questions
- How do you find the perimeter of a shape?
- What is perimeter?
- How do you find the perimeter of a rectangle?
- What is the difference between area and perimeter?
