Add & Subtract Decimal Numbers using the Standard Algorithm 5-102
Add and subtract using vertical, standard algorithms that focus on each digit's quantity and place value. What's .09 + .08? 9 hundredths + 8 hundredths = 17 hundredths = 1 tenth + 7 hundredths. Write a "7" in the hundredths place and a "1" in the tenths place. Write digits in the correct column with the correct place value.
