Video Solution

Solution Steps

00:11 Let's solve this problem together.
00:14 First, we follow the order of operations, starting with parentheses. Let's find that part first.
00:21 Next, solve from left to right, just like reading a book.
00:25 Take each step at a time, starting with the leftmost operation.
00:36 Let's rearrange everything to make solving easier for us.
00:41 Solve each multiplication separately. Then keep going until we're done.
00:47 And there you have it! That's the solution to our problem.

Step-by-Step Solution

According to the rules of the order of operations, we first solve the exercise within parentheses from left to right:

3215=17 32-15=17

1712=5 17-12=5

Now, we obtain the exercise:

5×34×12= 5\times34\times12=

According to the rules of the order of operations, since this is an exercise with only a multiplication operation, we rearrange the numbers to make the solution easier for us:

5×12×34= 5\times12\times34=

We solve the exercise from left to right:

5×12=60 5\times12=60

60×34=2040 60\times34=2040

Answer

2040
