What is the difference between word form and expanded form

When discussing integers, standard form refers to an integer written as a number, while word form describes an integer written out as a word. Expanded form uses different numbers in an equation to express the integer.

Word form is when u write it out and expanded form is when u use the number and multiple them with their value
For example:526
Expanded: (5x100) + (2x10)+ (6x1)
Word: five hundred twenty-six
