- Maths calculation: Arithmetic, fractions, ratios, powers and number bases at a steady pace.
Practising a memory task makes you better at that task. We make no claim about memory in daily life.
Quick lesson: Hexadecimal
Hexadecimal is base 16: digits run 0–9 then A–F (A = 10 … F = 15). Each place is worth 16 times the one to its right.
Check question
What is the hex number 1F in decimal?
- 15
- 25
- 31
- 115
Answer: 31. 1F = 1 × 16 + 15 = 31.
