What is integration in mathematics?
In mathematics, integration refers to the reverse of differentiation, used to find areas, totals and accumulated change. It matters because the same idea reappears across many later topics, so building a clear mental picture of it early saves a lot of time.
How to approach it step by step
To work with integration confidently, recognise the standard form, substitute where needed, and always add the constant of integration. LetMeTeach draws this out live on screen while explaining it aloud, so you watch each part appear instead of decoding a static block of text. You can interrupt at any point and ask for the same idea again in simpler words, in another language, or with a different example.
Worked example
∫2x dx = x² + C.
The mistake most learners make
Omitting the constant of integration in an indefinite integral.
