Question 1Aim for about 35 seconds

Work out the sum and give the answer as a letter.

A = 10, B = 2, C = 6, E = 7, F = 3. F + E = ?

Show the worked answer

Answer: A, A

How to work it out

  1. Swap each letter for its number: 3 + 7 = 10.
  2. The letter worth 10 is A.

Why the other options are wrong

  • B (B): B is worth 2, but 3 + 7 comes to 10, so the answer is not B.
  • C (C): C is worth 6, but 3 + 7 comes to 10, so the answer is not C.
  • D (E): Uses only E (7) and forgets to add F.
  • E (F): Uses only F (3) and forgets to add E.
Question 2Aim for about 35 seconds

Work out the sum and give the answer as a letter.

A = 3, B = 7, C = 6, D = 1, F = 10. C + D = ?

Show the worked answer

Answer: B, B

How to work it out

  1. Swap each letter for its number: 6 + 1 = 7.
  2. The letter worth 7 is B.

Why the other options are wrong

  • A (A): A is worth 3, but 6 + 1 comes to 7, so the answer is not A.
  • C (C): Multiplies C and D (6 × 1) when the sum is C + D.
  • D (D): Uses only D (1) and forgets to add C.
  • E (F): F is worth 10, but 6 + 1 comes to 7, so the answer is not F.

Question 3Aim for about 35 seconds

Work out the sum and give the answer as a letter.

A = 4, B = 6, C = 8, D = 2, E = 1. E × B − A = ?

Show the worked answer

Answer: D, D

How to work it out

  1. Swap each letter for its number: 1 × 6 − 4 = 2.
  2. The letter worth 2 is D.

Why the other options are wrong

  • A (A): A is one of the letters in the sum. The answer is the letter worth 2, the result of the working, not a letter from the question.
  • B (B): Works out E × B = 6 and stops, forgetting to take away A (4).
  • C (C): C is worth 8, but 1 × 6 − 4 comes to 2, so the answer is not C.
  • E (E): E is one of the letters in the sum. The answer is the letter worth 2, the result of the working, not a letter from the question.
Question 4Aim for about 35 seconds

Work out the sum and give the answer as a letter.

A = 9, C = 2, D = 12, E = 6, F = 8. A × C − D = ?

Show the worked answer

Answer: D, E

How to work it out

  1. Swap each letter for its number: 9 × 2 − 12 = 6.
  2. The letter worth 6 is E.

Why the other options are wrong

  • A (A): A is one of the letters in the sum. The answer is the letter worth 6, the result of the working, not a letter from the question.
  • B (C): C is one of the letters in the sum. The answer is the letter worth 6, the result of the working, not a letter from the question.
  • C (D): D is one of the letters in the sum. The answer is the letter worth 6, the result of the working, not a letter from the question.
  • E (F): F is worth 8, but 9 × 2 − 12 comes to 6, so the answer is not F.

Question 5Aim for about 35 seconds

Work out the sum and give the answer as a letter.

A = 6, B = 9, C = 5, D = 12, E = 2. E × B − 2 × A = ?

Show the worked answer

Answer: A, A

How to work it out

  1. Swap each letter for its number: 2 × 9 − 2 × 6 = 6.
  2. The letter worth 6 is A.

Why the other options are wrong

  • B (B): B is one of the letters in the sum. The answer is the letter worth 6, the result of the working, not a letter from the question.
  • C (C): C is worth 5, only one less than the 6 that the sum makes. Check each step of the working.
  • D (D): Takes away 6 once, but the sum takes away 2 × A, which is 12.
  • E (E): E is one of the letters in the sum. The answer is the letter worth 6, the result of the working, not a letter from the question.
Question 6Aim for about 35 seconds

Work out the sum and give the answer as a letter.

A = 8, B = 1, C = 5, D = 2, E = 4. A × D − 2 × E = ?

Show the worked answer

Answer: A, A

How to work it out

  1. Swap each letter for its number: 8 × 2 − 2 × 4 = 8.
  2. The letter worth 8 is A.

Why the other options are wrong

  • B (B): B is worth 1, but 8 × 2 − 2 × 4 comes to 8, so the answer is not B.
  • C (C): C is worth 5, but 8 × 2 − 2 × 4 comes to 8, so the answer is not C.
  • D (D): Adds A and D instead of multiplying them.
  • E (E): E is one of the letters in the sum. The answer is the letter worth 8, the result of the working, not a letter from the question.
