Multiplication and division: Addition, subtraction, multiplication and division

To solve $8 \div 2 \times 4$, you need to follow the order of operations: first perform the division and then the multiplication.

Step 1: Divide 8 by 2: $8 \div 2 = 4$

Step 2: Multiply the result by 4: $4 \times 4 = 16$

So, the answer is $16$.

According to the rules of the order of operations, the exercise which contains both multiplication and division should be solved from left to right.

$5-45+10=$

Finally we solve the exercise from left to right:

$5-45=-40$

$-40+10=-30$

According to the rules of the order of arithmetic operations, we must first place the multiplication and division exercises within parentheses:

$2-(6:2)+(5\times2)=$

We then solve the exercise inside of the parentheses:

$6:2=3$

$5\times2=10$

We obtain the following exercise:

$2-3+10=$

Finally we solve the exercise from left to right:

$2-3=-1$

$-1+10=9$

According to the rules of the order of arithmetic operations, we must first place multiplication and division exercises within parentheses:

$7+(3\times7)-(3\times4)+5=$

We then proceed to solve the exercise inside of the parentheses:

$3\times7=21$

$3\times4=12$

We obtain the following exercise:

$7+21-12+5=$

Lastly we solve the exercise from left to right:

$21+7=28$

$28-12=16$

$16+5=21$

According to the rules of the order of arithmetic operations, we begin by placing the multiplication and division exercises inside of parentheses:

$8+(3\times4)-2+1=$

We then solve the exercise within the parentheses:

$3\times4=12$

We obtain the following :

$8+12-2+1=$

Finally we solve the exercise from left to right:

$8+12=20$

$20-2=18$

$18+1=19$

According to the order of operations, we will first solve the multiplication exercises.

We will put them in parentheses so that we don't get confused later in the solution:

$25-(3\times4)+(4\times2)=$

Let's solve the multiplication exercises:

$3\times4=12$

$4\times2=8$

We get:

$25-12+8=$

Let's solve the exercise from left to right:

$25-12=13$

$13+8=21$

According to the rules of the order of arithmetic operations, we must first place the multiplication and division exercises within parentheses:

$(4\times7\times2:4)-(1\times9)=$

We then proceed to solve the exercise in parentheses from left to right:

$4\times7=28$

$28\times2=56$

$56:4=14$

We obtain the following exercise:

$14-9=5$

According to the rules of the order of arithmetic operations, we must first place multiplication and division exercises inside of parentheses:

$2+3-(15:3\times4)+6=$

We then solve the exercise within the parentheses from left to right:

$5-20=-15$

$-15+6=-9$

According to the order of operations, we place the multiplication and division exercise within parentheses:

$(9:3)-(1.5\times2)=$

Now we solve the exercises within parentheses:

$9:3=3$

$1.5\times2=3$

And we obtain the exercise:

$3-3=0$

According to the rules of the order of operations, multiplication and division precede addition and subtraction.

We isolate the multiplication exercise in parentheses and solve.

$(7\times3)=21$

Now, the exercise we're left with is: $21+8-4-7=$

We solve the exercise from left to right. We isolate the next part of the expression with parentheses to avoid confusion$(21+8)=29$

Now, the exercise obtained is: $29-4-7=$

We continue solving from left to right and isolate the next part of the expression in parentheses.

$(29-4)=25$

Now, the expression obtained is: $25-7=18$

According to the order of operations rules, we first insert the multiplication and division exercises into parentheses:
