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.
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
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
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.
4b plus 7b plus 5 will equal 11b plus 5. When you have two variables that are the same you can add the two numbers with the variables remaining the same.
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.
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.
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
It is not a law. It is the commutative property of numbers over addition.
They are: 25 times 25 = 625 or 312.5 plus 312.5 = 625
Equals means=ok
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...
An addition equation is the same thing even if the numbers are switched around.
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.
