3 less than the product of 9 and a number
Negative 6 is a bigger number than Negative 9 because Negative 6 is closer to zero, meaning that it is closer to becoming a positive whole number.
any negative number -n can be written as -1*n (minus 1 times that number). so, multiplying two negative numbers together:-n * -m = -1*n * -1*m = -1*-1*n*m = n*m (which is always positive)-6*-9 = -1*-1*6*9 = 6*9 = 54
-3^2 = 9 -(3^2) = -9
The square of any real number is non-negative. For example (-3)2 = +9 So, no real number can have a negative square root. Occasionally, though, mathematicians come across the need to find the square root of a negative number (for example in solving some quadratic equations). So they invented a family of numbers called imaginary numbers and the i (lower case) stands for the imaginary square root of -1. Apart from having a negative square, they are just like "ordinary" real numbers.
