If 2 numbers are different, but have the same absolute value, then one is the opposite of the other. Any number plus its opposite equals zero.

yes. An opposite number is the negative of a positive number, for example -5 and +5 are opposite numbers. Since minus x plus is minus and plus x minus is minus and plus x plus is plus and minus x minus is plus then the product of opposites is the same.

Yes - due to commutability, you can rearrange the numbers in any addition sum and the answer will still be the same.

This would be the commutative property of addition. It states that we can add the same numbers in any order and arrive at the same answer. I always tell my students the "C" in commutative stands for change as in changing the order of the numbers...

You can't really get two phone numbers on the same phone. But, you can get an extension phone number plus your regular phone number. Ask your phone service about an extension number for your phone.

They are: 25 times 25 = 625 or 312.5 plus 312.5 = 625

It means that it doesn't matter what order the numbers you are adding are in. A plus B is the same as B plus A. Contrast it with subtraction which does not have this quality.

An addition equation is the same thing even if the numbers are switched around.

When two numbers have the same sign, whether plus or minus, their product is positive. When two numbers have opposite signs, their product is negative.

No. The sequence of numbers we're given are odd numbers, and the sum of any three odd numbers will always be an odd number itself. Because 30 is an even number, you can not pick any three odd numbers that will add up to it.

Communicative Property of Addition. It is when two numbers are added and the sum is the same, regardless of their order.

It is not a law. It is the commutative property of numbers over addition.

Since the sum of two rational numbers is rational, the answer will be the same as for the sum of an irrational and a single rational number. It is always irrational.

The mean of a set of numbers is the average. That is to say, all the numbers added together and divided by the number of the numbers. the answer is 30.5

Yes, it is commutative. The result will be the same whatever the order of numbers and the operators are.3 + 4 + 3 + 6 + 4 = 20

6b+b+b is the same as 6b+1b+1b you can add the numbers together if the variables are the same. 6b+1b+1b=8b

impossible, they are all odd numbers, 5 x odd numbers will equal an odd number

Signed numbers are "plus" and "minus" numbers.

The median and mode of any number is the same number. The mode of 5 is 5, as is the median of 5. In other words, you need two or more numbers to determine the median and mode of those numbers.

Just add the numbers, and divide the result by 3 (since there are 3 numbers).

Impossible. They are all odd numbers. The sum of 5 odd numbers is also an odd number and cannot therefore total 50.

the addition property for 6 plus 7 equals 7 plus 6 is the commutative property. This property states that - when two numbers are added, the sum is the same regardless of the order of the addends.
