Question

24:8:3+262+19=? 24:8:3+2\cdot6\cdot2+19=\text{?}

Video Solution

Solution Steps

00:00 Solve
00:03 According to order of operations, we always solve from left to right
00:06 Each time we'll address the leftmost operation and solve it
00:09 Always solve multiplication and division before addition and subtraction
00:13 We'll continue solving from left to right, one operation at a time
00:25 And this is the solution to the question

Step-by-Step Solution

According to the rules for the order of operations, we will place multiplication and division exercises in parentheses:

(24:8:3)+(262)+19= (24:8:3)+(2\cdot6\cdot2)+19=

We solve the division exercises in parentheses from left to right:

24:8=3 24:8=3

3:3=1 3:3=1

We solve the multiplication exercises in parentheses from left to right:

2×6=12 2\times6=12

12×2=24 12\times2=24

Now we get the exercise:

1+24+19= 1+24+19=

We solve the exercise from left to right:

1+24=25 1+24=25

25+19=44 25+19=44

Answer

44
