## What is a sign diagram in math?

A sign diagram is a special type of table with two rows. The first row for indicating values of a variable x, say, and the second row for some expression involving the variable. For example, x squared minus x, which we factorize if possible. The line separating the rows is a copy of the real number line.

Bottom Line. You can teach yourself calculus. It won’t be easy and requires self-discipline and knowledge in algebra, geometry, and trig. However, the resources are out there, but the motivation must come from within.

## Why is calculus so hard?

Calculus is so hard because it requires a lot of hard work, mastery over algebra, is more conceptual than basic math courses, and has several highly abstract ideas. Students find calculus difficult because it is not always intuitive and requires tremendous background information.
