Math Subtraction

L.I to learn how to subtract numbers in different ways.
I learnt how to subtract equations in 3 of 4 separate ways. I learnt it by using a number line,Place value and more. The easiest one was the number line. I think the hardest was the place value. I worked with Charlize for this. I did 203 - 187 and she did 783 - 395. My answer for my equation was 16. Her answer was 388.
