Question

What does it mean to describe your solution approach using a mathematical expression? How might this be useful for finding errors, repetitive calculations or large projects?.

Answer 1

Definition of a mathematical expression: When we combine numbers and variables in a valid way, using operations such as addition, subtraction, multiplication, division, exponentiation, and other operations and functions as yet unlearned, the resulting combination of mathematical symbols is called a mathematical expression.

Mathematical expression can be in the simple form, i.e., arithmatic operation, algebraic, summation or some other form.

To describe the solution approach using mathematical expression means translating words in expression, eg. sum of x and 12 can be written as x+12 thus reducing the efforts and occupied space.

For a large project mathematical expression approach to find error is useful since large data is combined in small expression and then error calculation with these expression is less cumbersome. Summation form is widely used for findind errors and for repetitive calculation a general expresion can be formed rather than calculating again and again.

Hope this helps!
