Grade 7 Computer Science — Reading spreadsheet formulas
Read a spreadsheet formula, work out which cells it refers to, and say what number it will show.
Name: ________________________
1.The same sheet holds A1 = 4, A2 = 6 and A3 = 9. What number does the formula "=A3-A1" show?
2.A sheet holds A1 = 9 and A2 = 3, and a cell holding "=A1/A2" is showing 3. You then change A1 to 12. What does that cell show now?
- a) 3
- b) It keeps showing 3 until the formula is typed in again
- c) 4
- d) 12
3.A sheet holds A1 = 2, A2 = 5, A3 = 8 and A4 = 1. What number does the formula "=SUM(A1:A4)" show?
4.A sheet holds D1 = 12, D2 = 15 and D3 = 9. What number does the formula "=SUM(D1:D3)" show?
5.A sheet holds C1 = 20 and C2 = 4. What number does the formula "=C1/C2" show?
6.A sheet holds A1 = 10 and A2 = 4. Match each formula to the number it shows.
- =A1+A2
- =A1-A2
- =A1*A2
- =A1/A2
- =A2*A2
- 40
- 16
- 6
- 14
- 2.5
7.Sort each formula by whether it adds its cells together or multiplies them.
Groups: Adds · Multiplies
- =D1*D2
- =A1+A2
- =B2*B3
- =SUM(C1:C5)
- =E1*E2
- =A4+B4
8.A sheet holds B1 = 7 and B2 = 3. What number does the formula "=B1*B2" show?

- 1. 5
- 2. c) 4
- 3. 16
- 4. 36
- 5. 5
- 6. =A1+A2 → 14; =A1-A2 → 6; =A1*A2 → 40; =A1/A2 → 2.5; =A2*A2 → 16
- 7. =A1+A2 → Adds; =B2*B3 → Multiplies; =SUM(C1:C5) → Adds; =D1*D2 → Multiplies; =A4+B4 → Adds; =E1*E2 → Multiplies
- 8. 21
