The task: Using all the digits of the year 1492 only once and in the exact order that they appear in the year 1492, construct all numbers from 1 to 100! You can use any of the following operations: square root, factorials, exponents, decimals, parentheses, negative numbers, addition, multiplication, subtraction, division. Examples: 84 = 14 x √9 x 2 90 = (1+4) x 9 x 2 We still need the following numbers calculated: 40 41 49 59 61 62 64 The rest we’ve already calculated! Thanks for your help! Thanks from Spritofmaths

Interesting... $\displaystyle 40=1\times4+9^2$ $\displaystyle 41=(1+4)+9^2$ $\displaystyle 64=(1-\sqrt4+9)^2$ I'll leave the rest to Denis McField. Thanks from Math whiz

I-Fly has been doing a headstand, as 9² isn't 36. 40 = 14*√9 - 2 41 = -1 + 4! + 9*2 49 = (-1 + (√4)^(√9))^2 59 = -1 + 4*(√9)/.2 61 = -1 + 4^(√9) - 2 62 = 1*4^(√9) - 2 64 = (1*(√4)^(√9))^2 Thanks from Denis, Joppy and Math whiz

Sure is! I'll start:

1 = -1 * 4 + √9 + 2
2 = -1 - 4 + 9 - 2
3 = 1 * √4 + √9 - 2
4 = -1 - √4 + 9 - 2
5 = -1 * √4 + 9 - 2
