Notes

All daily items change at midnight GMT (it is roughly 1:16 PM GMT). Change.

• 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)
• x 3/5   find three fifths (e.g. 1/5 of 15 = 3, so 3/5 = 9)
• x 21/3  find two and a third (e.g. 2 1/3 of 15 = 2 x 15 + 5 = 35)
• x 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. You can use a calculator to see the value at each stage of the calculation.
