• 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)
