Fascinating Fact:

The height of Mount Everest at 8849 metres minus Ben Nevis at 1345 metres leaves 7504 metres, about 85 Big Bens tall.

In 11 Plus Maths, subtraction and addition are used to solve everyday problems and build mental agility. These core operations help pupils prepare for topics like percentages and algebra.

  • Difference: The result when one number is taken away from another.
  • Carry Over: When a value moves to the next column during addition.
  • Operation: A mathematical action such as addition, subtraction, multiplication, or division.
How can subtraction help me in daily life?

Subtraction helps you find what’s left, compare costs, check totals, and solve word problems in shopping, travel, or time questions.

What is the difference between addition and subtraction?

Addition combines numbers to make a larger total, while subtraction removes one quantity from another to find what remains.

Do addition and subtraction appear in every 11 Plus paper?

Yes, they appear in most 11 Plus Maths papers, often within word problems or reasoning questions that test logic and accuracy.

1 .
364 – 88 + 5 + 17 = ?
294
296
298
300
It's a good idea to add the hundreds first, then the tens and finally the ones: 364 – 88 + 5 + 17 = (300) + (60 + 10 - 80) + (4 + 5 + 7 - 8) = (300) + (70 - 80) + (16 - 8) = 300 - 10 + 8 = 298
2 .
214 + 67 + 734 - 19 = ?
995
996
997
998
Remember to add the 100s, then 10s and finally ones. If you aren't sure of your answer, you can do the procedure again to double check
3 .
897 + 328 - 478 = ?
747
748
749
750
897 + 328 - 478 = (800 + 300 - 400) + (90 + 20 - 70) + (7 + 8 - 8) = (700) + (40) + (7) = 747
4 .
376 - 597 + 233 = ?
6
12
18
24
To avoid working with negative numbers, you can rearrange the problem: 376 - 597 + 233 = (376 + 233) - 597 = 609 - 597 = 12
5 .
608 + 753 - 487 = ?
871
872
873
874
With numbers less than 1,000, add the hundreds first, then the tens and then the ones. 608 + 753 - 487 = (600 + 700 - 400) + (50 - 80) + (8 + 3 - 7) = (900) + (-30) + (4) = 874
6 .
546 + 395 – 142 = ?
801
800
799
798
In multiple choice quizzes, the last digit in a number can show you the right answer. 6 + 5 - 2 = 9, so the last digit in 546 + 395 – 142 will also be a 9
7 .
720 – 703 – 300 + 821 = ?
538
539
540
541
Always look out for shortcuts: the 700s in 720 – 703 cancel each other out, making the answer the same as 20 - 3
8 .
700 + 100 + 300 – 786 = ?
214
264
314
324
700 + 300 = 1,000. keep your eyes peeled, looking for ways to break the problem up into smaller sums
9 .
354 – 75 – 83 + 248 = ?
434
444
454
464
Remember, 100s first, then 10s, then ones: 354 – 75 – 83 + 248 = (300 + 200) + (50 + 40 - 70 - 80) + (4 + 8 - 5 - 3) = (500) + (-60) + (4) = 444
10 .
147 + 476 – 38 = ?
582
583
584
585
7 + 6 - 8 = 5, so you know that the answer to 147 + 476 – 38 will also end with a 5
