Fascinating Fact:

If you swap the numbers around in addition, the answer stays the same, like flipping a pancake that lands perfectly.

In 11 Plus Maths, pupils learn that addition and subtraction are opposite operations. When adding, numbers increase, and when subtracting, they decrease. Understanding how these two work together builds the foundation for more advanced problem solving, such as working with decimals, fractions, and algebra later on.

Key Terms

Addition: The process of finding the total when two or more numbers are combined.
Subtraction: The process of finding how much remains when one number is taken away from another.
Inverse: The mathematical opposite; subtraction is the inverse of addition.

Frequently Asked Questions (Click to see answers)

What is the rule for addition?

When adding numbers, the order does not matter. For example, 6 + 4 gives the same result as 4 + 6.

How is subtraction different from addition?

Addition increases a number’s value, while subtraction decreases it. They are opposite or inverse operations.

Why is subtraction important in maths?

Subtraction helps us find differences, calculate change, and solve everyday problems involving taking away or comparing amounts.

1 .

12 + 6 - 2 = ?

TIP: With numbers less than 100, add the tens first and then add the ones. 12 + 6 - 2 = (10) + (2 + 6 - 2) = 10 + 6 = 16

2 .

23 + 6 - 4 = ?

23 + 6 - 4 = (20) + (3 + 6 - 4) = 20 + 5 = 25

3 .

10 + 23 + 5 - 1 = ?

10 + 23 + 5 - 1 = (10 + 20) + (3 + 5 - 1) = 30 + 7 = 37

4 .

17 - 8 = ?

17 - 8 = (10) + (7 - 8) = 10 - 1 = 9

5 .

46 - 20 + 12 = ?

46 - 20 + 12 = (40 + 10 - 20) + (6 + 2) = 30 + 8 = 38

6 .

12 + 12 + 12 = ?

12 + 12 + 12 = (10 + 10 + 10) + (2 + 2 + 2) = 30 + 6 = 36. Obviously, if you know that 12 × 3 = 36, you won't follow this procedure. Always BE ON THE LOOKOUT for short cuts

7 .

34 + 15 + 6 - 1 = ?

34 + 15 + 6 - 1 = (30 + 10) + (4 + 5 + 6 - 1) = 40 + 14 = 54

8 .

2 + 4 + 6 + 7 + 1 = ?

2 + 4 + 6 + 7 + 1 = (4 + 6) + (7 + 2 + 1) = 20. Try to group your numbers in lots of ten

9 .

0 + 2 + 12 + 0 = ?

0 + 2 + 12 + 0 = (10) + (2 + 2) = 10 + 4 = 14. You could do this sum just by looking at it

10 .

8 + 14 - 8 + 6 = ?

8 + 14 - 8 + 6 = (14 + 6) = 20. Cross out identical pairs of numbers that differ only in sign, e.g. +8 - 8 = 0. Don't waste your time adding them to your final calculations
