10 year olds math assignment challenge!

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!

Another game, eh? 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

Perhaps Monox D. 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

Oops, guess I am being stoned when doing my headstand. Well, at least my answer for 64 was correct, so my post didn't go in vain.
