The square root (r) of a number (y) is that number which multiplied by itself gives the original number, ie:
if r = √y, then y = r × r = r².
Every number has two square roots as a negative number multiplied by a negative number is a positive number.
Examples:
√16 = 4 or -4 (written as ±4) since 4 × 4 = 16 and -4 × -4 = 16
√25 = ±5
√2.25 = ±1.5
Negative numbers do not have real square roots. They have complex square roots which are the square root of the positive number multiplied by the square root of -1 which is written as "i", examples:
√-1 = i
√-16 = ±4i
