How would you explain to a seventh grader the difference between the domains of an odd root radical function and an even root radical function?
To start with, when you multiply an even number of negative numbers, the answer is positive. When you multiply an odd number of negative numbers, the answer is negative. When you multiply any number of positive numbers, the answer is always positive. For positive numbers, the value of a power is always positive. For negative numbers, the value of an odd power is negative, and the value of an even power is positive. Finding roots is the inverse of taking powers, so that an odd-root function can be evaluated for any value of x. An even-root function, however, cannot be evaluated when the value of x is negative, since an even power can never result in a negative answer. The domain of an odd root function is all real numbers; the domain of an even root function is the non-negative real numbers.
How do you type in minus numbers into a calculator?
Most calculators have a +/- (+ is positive, - is negative) symbol on them, which allows you to use the negative function. To do so, simply key in the number, then hit the +/- sign, which will then put the number in negative (minus) status. But if you already have a negative number, for example if you key in 25 - 30, you will have a -5, then you can hit the symbol to make it a positive number if that's what you want. In other words, when you hit that function, it will give you the opposite of what's in it at the time. For example, if the display shows a positive number and you hit that function, you will then have a negative number. If it shows a negative number and you hit that function, you will then have a positive number.
Is negative 11 an integer?
Yes the integer group includes negative numbers, positive numbers, and 0.
How are negative numbers applied today?
One common example is temperatures below 0. These are negative numbers.
Why are the negative numbers not a whole number?
They can be. For example, -3 is a negative whole number.
What happens when you use the Sum function and in the range of cells you find negative numbers?
It will still perform the calculation. The SUM function can deal with positive and negative numbers and it will deal with negative numbers correctly. So there will be no problems or errors if there are negative numbers amongst the numbers in the range of cells that it is calculating.
What type of numbers is the sum of two negative numbers?
They will be negative numbers as for example -5+(-7) = -12
When a number written in scientific notation includes a negative exponent is the number negative?
No, if there is a negative number then you put that many numbers before the root number. For example, 7x10^-5= .000007
Is negative sixteen an integer?
Yes. "Integer" includes positive numbers, negative numbers, and zero.
Is negative 14 an irrational number?
Whole numbers are RATIONAL. That includes negative whole numbers.

True or False The category of numbers called integers includes negative numbers?
It is false. It does not include negative fractional numbers.

Is negative 11 an integer?
Yes the integer group includes negative numbers, positive numbers, and 0.
Can the mode and median be a negative number?
Yes, but only if the data set includes some negative numbers. For example, recording winter temperatures at the South Pole. They will all be negative (or most of them will be) so the mode and the median will be negative as well.
Why are there negative numbers?
Because there are negative values as for example the temperature can be -12 Centigrade
