There are infinitely many expressions. For example,-48 -50, -47 -51, -46 -52, -45 -53 and so on - forever.
Then look at numbers to 1 decimal place:
-48.9 -49.1, -48.8 - 49.2 and so on.
Then numbers to 2 decimal places, 3 dp, 4 dp, ... infinitely many dp.
Next you can consider triplets of number rather than pairs. And then sets of 4 numbers, 5 numbers and so on to infinitely many numbers - in each case looking at numbers with 0 dp, 1dp, etc.
You can then move on to subtractions, and then multiplications and divisions.
And then there are other operations, for example, log(100/googol).

What is the definition of an equivalent variable expressions?
An equation if both expressions are equal
What is the definition of equivalent numerical expressions?
That means that the two expressions represent the same number.
When two expressions have the same value they are?

How are equivalent expressions used?
You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.
