Fascinating Fact:

It would take just over 3 Big Bens stacked to match the Eiffel Tower.

In 11 Plus Maths, pupils build fluency in addition and subtraction to support problem-solving and mental arithmetic. These skills form the base for fractions, ratios, and algebra.

  • Column Addition: A method of adding numbers by lining up the digits in columns.
  • Borrowing: Taking a value from the next column to complete a subtraction.
  • Place Value: The value a digit has based on its position in a number.
What is the best way to practise subtraction?

Start with small numbers and work up. Try using number lines or column subtraction to keep digits organised and avoid mistakes.

What does ‘borrowing’ mean in subtraction?

Borrowing is when you take 1 from the next column to help subtract when the top digit is smaller than the bottom one.

Are these skills used in harder maths topics?

Yes. Addition and subtraction form the foundation for learning about fractions, algebra, percentages, and more advanced calculations.

1 .
22 - 38 + 45 = ?
29
28
30
31
TIP: With numbers less than 100, add the tens first and then add the units.
22 - 38 + 45 = (20 + 40 - 30) + (2 + 5 - 8) = 30 + -1 = 29.
Remember: if you are adding a minus number, that’s the same as subtracting a positive number
2 .
47 + 15 + 73 = ?
125
135
145
155
TIP: With numbers less than 100, add the tens first and then add the units.
47 + 15 + 73 = (40 + 10 + 70) + (7 + 5 + 3) = 120 + 15 = 135
You may have noticed another shortcut: 7 + 3 = 10 so 47 + 73 = 40 + 70 + 10
3 .
6 - 12 + 27 + 33 = ?
58
56
54
52
TIP: With numbers less than 100, add the tens first and then add the units.
6 - 12 + 27 + 33 = (20 + 30 - 10) + (6 + 7 + 3 - 2) = 40 + 14 = 54
Be on the lookout for simple calculations that make your life easier! 27 + 33 is one of these
4 .
34 + 0 + 58 + 17 - 0 + 5 = ?
110
124
104
114
TIP: With numbers less than 100, add the tens first and then add the units.
34 + 0 + 58 + 17 - 0 + 5 = (30 + 50 + 10) + (4 + 8 + 7 + 5) = 90 + 24 = 114. Ignore zeros!
5 .
27 - 68 + 59 - 9 = ?
9
11
-9
7
TIP: With numbers less than 100, add the tens first and then add the units.
27 - 68 + 59 - 9 = (20 + 50 - 60) + (7 + 9 - 8 - 9) = 10 + -1 = 9
Remember: if you are adding a minus number, that’s the same as subtracting a positive number
6 .
23 + 37 + 53 = ?
103
113
93
123
TIP: With numbers less than 100, add the tens first and then add the units.
23 + 37 + 53 = (20 + 30 + 50) + (3 + 7 + 3) = 100 + 13 = 113
Don't forget: sometimes you will spot an easy addition which will make the calculation easier, e.g. 23 + 37 = 60
7 .
74 - 98 + 29 = ?
201
-5
5
15
TIP: With numbers less than 100, add the tens first and then add the units.
74 - 98 + 29 = (70 + 20 - 90) + (4 + 9 - 8) = 0 + 5 = 5
A quick way to subtract 98 is to subtract 100 then add 2
8 .
15 + 15 - 15 + 15 = ?
60
15
45
30
That was an example of a question you must read thoroughly - you didn't think all the 15s were to be added did you?
9 .
54 - 27 = ?
26
27
28
29
TIP: With numbers less than 100, add the tens first and then add the units.
54 - 27 = (50 - 20) + (4 - 7) = 30 + -3 = 27
Another way to do this is to subtract 30 then add 3: 54 - 30 = 24. 24 + 3 = 27
10 .
26 + 47 = ?
63
83
53
73
TIP: With numbers less than 100, add the tens first and then add the units.
26 + 47 = (20 + 40) + (6 + 7) = 60 + 13 = 73
Another way to add 47 is to add 50 then subtract 3: 26 + 50 = 76. 26 - 3 = 73
