Addition, Subtraction, Multiplication and Division: Solving the problem

Division and multiplication are on the same level of order of operations,

therefore, when encountering such a case, we will always solve from left to right.

10*2=20

20/4=5

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

$30:5=6$

$6\times2=12$

According to the order of operations rules, we will solve the exercise from left to right since the only operations in it are addition and subtraction:

$10-3=7$

$7+7=14$

$14-5=9$

According to the rules of the order of operations we should first solve the exercise from left to right since it only contains a division operation:

$80:4=20$

$20:2=10$

$10:5=2$

According to the order of operations, we first put the multiplication exercise in parentheses to avoid confusion in the rest of the solution:

$(25\times6)-9-41=$

Let's solve the multiplication exercise first:

$150-9-41=$

Now let's solve the exercise from left to right:

$150-9=141$

$141-41=100$

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

$(5\times5\times2)-(12:4)=$

Now let's solve the exercises in parentheses from left to right:

$5\times5=25$

$25\times2=50$

$12:4=3$

Now we get the exercise:

$50-3=47$

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

$(24:2)-4-(3:3)=$

Let's solve the exercises in parentheses:

$24:2=12$

$3:3=1$

Now we have the expression:

$12-4-1=$

Let's solve the expression from left to right:

$12-4=8$

$8-1=7$

According to the order of operations rules, we will solve the exercise from left to right since the only operations in it are addition and subtraction:

$90-2=88$

$88+9=97$

$97-8=89$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$25+6=31$

$31-19=12$

$12+7=19$

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 for the order of operations, we will isolate the multiplication and division exercises in parentheses:

$(14:2\cdot5:7)+12+25=$

We solve the exercise in parentheses from left to right:

$14:2=7$

$7\times5=35$

$35:7=5$

Now we obtain the exercise:

$5+12+25=$

We solve the exercise from left to right:

$5+12=17$

$17+25=42$

According to the rules of the order of operations, we solve the exercise from left to right since the exercise only involves multiplication and division:

$80:10=8$

$8:5=\frac{8}{5}$

$\frac{8}{5}\times5=8$

$8:25=\frac{8}{25}$

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

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

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

$24:8=3$

$3:3=1$

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

$2\times6=12$

$12\times2=24$

Now we get the exercise:

$1+24+19=$

We solve the exercise from left to right:

$1+24=25$

$25+19=44$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$25-6=19$

$19-9=10$

$10+7=17$

$17-3=14$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$14-5=9$

$9-9=0$

$0+7=7$

$7+2=9$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$26-6=20$

$20+9=29$

$29+7=36$

$36-12=24$

Insofar as the exercise only involves addition and subtraction operations, we will solve it from left to right:

$30+6=36$

$36-5=31$

$31+7=38$

$38-17=21$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$25-5=20$

$20-3=17$

$17-17=0$

$0+13=13$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$32-4=28$

$28-19=9$

$9+3=12$

$12-7=5$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$21-3=18$

$18-6=12$

$12+9=21$

$21-5=16$
