A binary operation is one which takes two numbers and combines them into one. +,-,* and / are all binary operations.
If you start with 4 numbers and apply one binary opeartion (to two of the numbers) you are left with three. After two binary operations you are left with two numbers and after three binary operations you are left with only one number. You cannot, therefore, carry out the fourth binary operation if you start with four numbers.
Adding is when you add numbers to something and subtracting is when you take them away. When you add you do not always make the number go up for example 5 + (-7)= -2.
They can if the binary operation is multiplication or division.
Two negatives make a positive in multiplication and division
They are not the same: they are similar. Division is the inverse operation. Division by x (where x is non-zero) is the same as multiplication by (1/x). So the operations are related but that does not make them the same.
In multiplication and division: always. In addition: never. In subtraction: sometimes.
Division is the inverse operation to multiplication.
You are thinking of Pythagoras and fermat type jobbies. 32+42=52 (9+16=25)
heat. adding or subtracting
Class we are going to learn division. Hope you learn your multiplication.

divide 28 by 4
They can if the binary operation is multiplication or division.

When adding- yes When subtracting-no When multiplying-no When dividing-yes
We can calculate this quickly by subtracting by 1000 (over-subtracting) and then adding 4 to make up for it. Thus we get 1003 + 4 = 1007.
multiply seven by 2 which is fourteen
They are not the same: they are similar. Division is the inverse operation. Division by x (where x is non-zero) is the same as multiplication by (1/x). So the operations are related but that does not make them the same.
