Why does the product of 4 negative numbers equal a positive?
If you know that the product of 2 negative numbers is positive, then the product of 4 negative numbers has to be positive. The product of the first two negative numbers is positive and the next two negative numbers is positive. Multiplying the product of the first two numbers (positive number) and the product of the last two numbers (also positive), is a positive number times a positive number which is positive. Let a, b, c and d be negative numbers: (a*b*c*d) = (a*b)*(c*d) (-ve*-ve*-ve*-ve)=(-ve*-ve)*(-ve*-ve)= (+ve)*(+ve) = (+ve)
What happen when you divide negative and positive number?
When you divide or multiply positive and negative numbers, you first do the division or multiplication as normal. The next step is to assess whether or not the answer will be negative or positive. If the two numbers of the question were the same (negative and negative or positive and positive) then the answer will be positive. If the two numbers in the question were different (one negative and one positive) then the answer will be negative. Thus, if you divide a negative number by a positive number, the result will be the same as normal division, but the answer will be negative.
How you would order from least to greatest three numbers that include a positive number a negative number and zero?
Negative first, then zero and then the positive.
Why does the product of 3 negative numbers equal a negative number number?
Because two negative multiplied together equal a positive. So after the first multiplication we have a positive and a negative. When we multiply these we have a negative.
How can you compare rational numbers?
Subtract one from the other.If the answer is positive then the first is larger,if the answer is negative, then the second is larger.Rational numbers are numbers that can be expressed as fractions whereas irrational numbers can't be expressed as fractions.
