In order to simplify our calculation, we first break down 93 into smaller, more manageable parts. (Preferably round numbers )
We obtain the following:
We then use the distributive property in order to find the solution.
We multiply each of the terms in parentheses by 3:
Lastly we solve each of the terms in parentheses and obtain:
279
\( 100-(30-21)= \)
You absolutely can! But breaking it down with the distributive property makes the calculation easier, especially with larger numbers. Both methods give the same answer: 279.
Look for numbers close to multiples of 10 (like 90, 100, 200). For 93, we chose 90 + 3 because 90 is easy to multiply and 3 is what's left over.
That's fine! You could write 93 as 80 + 13 or 50 + 43. The distributive property works with any valid breakdown, though some make calculations easier than others.
It depends on what your teacher asks for! Showing the steps demonstrates your understanding, but once you're comfortable, you can do simpler multiplications mentally.
Try the multiplication a different way! You could use long multiplication or break 93 down differently. You could also use division: ✓
