If two numbers are multiplied and one of them is negative, the answer will turn out negative. If the two numbers being multiplied are either both negative or both positive, the answer will turn out positive. Example: -2 * 2 = -4 -2 * -2 = 4 2 * 2 = 4
When multiplying numbers with exponents, you add the exponents.
(-1)2=1 all squared numbers turn out positive and 12=1 (-1)2=1 all squared numbers turn out positive and 12=1
They can, but they are called imaginary numbers. This is because a "square" of something is the number that, when multiplied by itself, will equal the first number. A negative multiplied by a negative equals a positive, and positives can't turn into negatives on their own, so there are no square roots of negative numbers.
cause with negitives, once they are multiplied it cancles out. We say the multiplication is a short hand of a repeated addition. For example 3(5) means the number five shows up three times in the addition such as 5 + 5 + 5. So to turn (-2) + (-2) + (-2) + (-2) into a multiplication we count the times that -2 takes place in the addition, and we write 4(-2). If we have -4(-2), it means that we are looking for the opposite (or the negative) of 4(-2), because the first number in a multiplication is just a counting number which is always positive. Therefore, -4(-2) = -[4(-2)] = -(-8) = 8. Thus, we can say multiplying two negative numbers yields a positive number.
If two numbers are multiplied and one of them is negative, the answer will turn out negative. If the two numbers being multiplied are either both negative or both positive, the answer will turn out positive. Example: -2 * 2 = -4 -2 * -2 = 4 2 * 2 = 4

No, they cannot. The result of some operations on positive numbers can be negative.
Negative times negative equals positive. Positive times positive equals positive. Positive times negative equals negative. If you have more than two numbers, multiply the first two and then apply these rules to each successive number in turn.
(-1)2=1 all squared numbers turn out positive and 12=1 (-1)2=1 all squared numbers turn out positive and 12=1
To turn a negative y into a positive y in slope, you can multiply the entire equation by -1. This will change the sign of the y term from negative to positive. For example, if you have a slope equation of y = -2x, multiplying by -1 gives you y = 2x, which changes the negative y to a positive y.
No , but a negative test can be a false positive .
To turn a negative number into a positive number...you can either multiply/times two negative numbers (eg -2 x -2 = 4) together or subtract a negative number (eg 3-(-3) = 3+3=6)
They can, but they are called imaginary numbers. This is because a "square" of something is the number that, when multiplied by itself, will equal the first number.

It will turn into A negative number.
To turn a negative attitude into a positive one it is important to lead by example. A child will watch you and if they see you being positive they will also be positive.
You could use the ABS function which takes a number and ignores its sign, so it can turn negative numbers into positive ones. So for example, the following will result in 5: =ABS(-5) You can also put a minus before a minus number to make it positive: --5
