Answer 1

What are Mathematical expressions?

An expression is a set of terms combined using the operations +, – , x or. , for example 4 x − 3 or x 2 – x y + 17 . An equation states that two expressions are equal in value, for example. 4 b − 2 = 6 . An identity is a statement that is true no matter what values are chosen, for example.

How They Do Work?

To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ. ... The mathematical expression for work depends upon the particular circumstances.

Answer 2

Answer:

mathematical expressions is to use variables or algebra in a valid and proper way with BODMAS operations or someother ones . combined mathematical symbols are mathematical expressions.
