In subtraction, you cannot subtract a larger number from a smaller one in the same place value. Borrowing lets you 'trade' 1 from the next column for 10 in the current column!
The 8 becomes 7 because you borrowed 1 from it. Think of it like trading one 10 bills - you have one less hundred but ten more tens.
Always borrow from the left! Move from the place value that's having trouble to the next larger place value on its left side.
