According to the order of operations rules, since the exercise only has multiplication, we will solve the exercise from left to right.
We will solve the left exercise in vertical multiplication format to make the solving process easier for ourselves.
It's important to maintain the correct order of solving, meaning first multiply the ones digit of the first number by the ones digit of the second number,
then multiply the tens digit of the first number by the ones digit of the second number, and so on.
Now we will get the exercise:
We will solve this exercise vertically as well, following the same rules as we did in the previous exercise.
\( 13+5+5= \) ?
Yes! When you have only multiplication, follow the left-to-right rule. This keeps your calculations organized and prevents errors with larger numbers.
Actually, yes! Because of the commutative property, you could calculate first, then . You'll get the same answer!
If you get the first step wrong, your final answer will be completely incorrect! Always double-check each multiplication step before moving to the next one.
Use vertical multiplication! Write 105 on top, 24 below, then multiply 105 by 4, then by 20, and add the results: 420 + 2100 = 2520.
Make sure you're entering the multiplication correctly! Check that you typed 35 × 3 × 24 and not 35 + 3 × 24, which would give 107 due to order of operations.
