Notes

All daily items change at midnight GMT (UTC+0).

HALVE divide by 2 (e.g. 10 ÷ 2 = 5)
DOUBLE multiply by 2 (e.g. 10 x 2 = 20)
SQUARE times by itself (e.g. 10 x 10 = 100)
CUBE times by itself twice (e.g. 10 x 10 x 10 = 1,000)
×³/₅ find three fifths (e.g. ¹/₅ of 15 = 3, so ³/₅ = 9)
×2¹/₃ find two and a third (e.g. 2 ¹/₃ of 15 = 2 x 15 + 5 = 35)
×10% find 10% (e.g. 10% of 80 = 8)
√ find the square root (e.g. the square root of 100 is 10)

I have deliberately chosen not include the answers - but you could use a calculator to see the value at each stage of the calculation.
