What do standard form mean in mathematical terms?

Answer 1

standard form means showing numbers in their normal state.

Example- if 3,976 is in expanded form, it would look like this: 3,000 + 900 + 70 + 6

So if a question on a math worksheet asked you what that number would look like in standard from, it would look like this: 3,976- you just took the 0's off of the numbers and put them together.
