In order to find the mean of numbers, add up all of the numbers and thn divide it by the number of numbers there are. Adding two, five and twelve equals nineteen. Then divide three into nineteen, and this gives you a mean of 6.33.
120 plus 120 equals 240, or 240 plus 0 equals 240, and keep on adding!
Adding two or more numbers together gives you a sum.
No, five is a prime number because there are only two whole numbers that when multiplied, equals five. (Those numbers are five and one.) In order for a number to be composite, it has to have factors other than itself and one.
The result of adding two numbers is their sum.
a difference
the PRODUCT :)
Then you are adding two rational numbers with different signs! No big deal!
+ is the symbol for adding two numbers together.It is usually called the plus symbol.
The two numbers that satisfy the given conditions are 4 and 1. When you add 4 and 1, you get 5. When you multiply 4 and 1, you get 4. The two numbers are 4 and 1.
Never. The sum of two negative numbers is a negative number with a value less than either of them, e.g. (-1) + (-2) = (-3) Adding two negative numbers is the same as adding their positive absolute values, and expressing the sum as a negative. If the two negative numbers are the same, and you subtract one from the other, the result is 0. e.g. (-2) - (-2) is the same as (-2) + 2 , which equals 0.
9.9 is the answer. You get it by ignoring the minus signs and then adding the two numbers. So 4.2 + 5.7 equals 9.9.
