what is the square root of sixteen. I was wondering if anyone knows this answer. I have recently been learning the language of math and i dont understand exactly how numbers work. So they go 1 2 3 4 5 6 7 8 9 10 101 102 103 104 105 106 107 108 109 110. why do they go straight to 3 digits? please help me i am very confused. My brain is going to explode.
