What is the smallest number subtracted from 629 to give a perfect square?
The answer is 4, as 629 minus 4 equals 625. 625 is 25 squared.
What number when multiply by itself equals 60?
that is the square root of 60 which is not an integer. It is about 7.746
Does a negative number minus a positive number equal a positive or a negative?
A negative number minus a positive number equals a minus number( E.G -5 - [+]5 = -10)A negative number minus a negative number equals a positive number ( If the number's big enough)(E.G -5 - -5 = 0 )Hope this helps :)

What is a square root of a square?
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
How does square root work?
The idea is to find a number which, when square, equals the given number. For example, asking for the square root of 100 means solving the equation x2 = 100. The solution, in this case, is 10. (Minus 10 is also a solution, but the term "square root" refers to the positive solution in this case.)The idea is to find a number which, when square, equals the given number.

If sin2a plus cos2a equals 1 does sin2a minus cos2a equals 1 also ... 2 means square and a means alpha?
No. But sin2a equals 1 minus cos2a ... and ... cos2a equals 1 minus sin2a
What number equals the number of centimeters in a meter minus the number of inches in a yard?
The centimeters in a meter (100) minus the inches in a yard (36) equals 64.
What times itself equals minus?
In order to represent the square root of a minus number (which does not in fact actually exist other than as an abstract notion), mathematicians use an imaginary number called "i". i represents the value of the square root of -1. We must remember that it is not a real number, which is why we call it imaginary.So to answer your question, i, or a multiple of i, times itself equals a minus number.For example 2i * 2i = -4 (this is because we can rewrite -4 as 4 * -1. The square root of 4 is 2 and the square root of -1 is i. Therefore the square root of -4 is 2i).
Even number minus an odd number equals?
