Description: You can write the numbers 1 through 10 using ONLY the digits 1 and 9... and eventually it gets a little complicated if you try not to repeat any terms. You can use any signs or notation, but you're limited to just 1 and 9 on the numbers. So, 11 = 9 + 9/9 + 1, and 12 = 9^1 + the square root of 9... and 13 = OKAY YOU DO IT #shorts
