Rule 2: A negative number times a positive number equals a negative number. When you multiply a negative number to a positive number, your answer is a negative number. It doesn’t matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.
What happens when you square a negative X?
Answer: Yes. If a number is squared, it becomes positive. The square of a number can be found by multiplying the number by itself. Explanation: The product of two negative numbers is always positive. If we find the square of a negative number, say -x, where x > 0, then (-x) × (-x) = x2.
What happens when you divide a negative by a positive?

Is negative 2 squared positive or negative?
In fact, any number at all can be squared, even numbers like pi and 0. This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2)(-2) = 4. Note that this is positive because when you multiply two negative numbers you get a positive result.
What are the rules for dividing negative numbers?
When you divide two negative numbers, the answer is always a positive number. For example, -4 divided by -2 equals 2. When both numbers are negative, the negatives cancel out, resulting in the answer always being a positive number.
How do you change a negative exponent to a positive?
When we need to change a negative exponent to a positive one, we are supposed to write the reciprocal of the given number. So, the negative sign on an exponent indirectly means the reciprocal of the given number, in the same way as a positive exponent means the repeated multiplication of the base.
Can I divide by a negative number?
Multiplication and division with negative numbers is virtually the same as with positive numbers. The only question is whether the sign is positive or negative. Just remember that when you multiply or divide two numbers, If the numbers have the same sign, the result is always positive.
How do you square a negative number to get a positive?
Squaring a positive number gets a positive result: (+5) × (+5) = +25. Squaring a negative number also gets a positive result: (−5) × (−5) = +25. Because a negative times a negative gives a positive. So: “So what?”.
