Multiplication and division - Examples, Exercises and Solutions

The given equation is $36 - 4 \div 2$. To solve this, we must follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

Step 1: Division

• Identify the division operation in the equation: $4 \div 2$.

• Perform the division: $4 \div 2 = 2$.

Now the equation becomes: $36 - 2$.

Step 2: Subtraction

• Perform the subtraction: $36 - 2 = 34$.

Therefore, the result of the equation $36 - 4 \div 2$ is $34$.

The division and multiplication have the same priority according to the order of operations, therefore we solve it from left to right:

$10\cdot2=20$

$20/4=5$

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, you should first calculate the multiplication, then the addition:

$4 \times 2 = 8$

Then add the result to 3:

$3 + 8 = 11$

First perform the multiplication:

$9 \times 2 = 18$

Then subtract 4:

$18 - 4 = 14$

First, perform the division:

$6 / 2 = 3$

Then add 5:

$3 + 5 = 8$

According to the order of operations, multiplication should be performed before addition. So, first calculate the multiplication:

$5 \times 3 = 15$

Then add 2 to the result:

$2 + 15 = 17$

Therefore, the correct answer is:

$17$

First, perform the multiplication operation:

$6 \times 2 = 12$

Then subtract 4 from the result:

$12 - 4 = 8$

Therefore, the correct answer is:

$8$

According to the order of operations, both addition and subtraction can be solved from left to right. So, first subtract 3 from 9:

$9:3=3$

Then add 2 to the result:

$3+2=5$

Therefore, the correct answer is:

$5$

First, perform the multiplication operation:

$5 \times 2 = 10$

Then add 1 to the result:

$10 + 1 = 11$

Therefore, the correct answer is:

$11$

To solve the expression $5 + 3 \times 2$, we follow the order of operations (PEMDAS/BODMAS).

1. First, we perform the multiplication:

$4\times2=8$

2. Next, we add the result to 5:

$5+8=13$

Therefore, the final answer is $13$.

First, we calculate the product of the first two numbers: $3 \times 2 = 6$.

Then, we multiply the result by the third number: $6 \times 4 = 24$.

Therefore, $3 \times 2 \times 4 = 24$.

First, we calculate the product of the first two numbers: $2 \times 5 = 10$.

Then, we multiply the result by the third number: $10 \times 3 = 30$.

Therefore, $2 \times 5 \times 3 = 30$.

First, we calculate the product of the first two numbers: $4 \times 3 = 12$.

Then, we multiply the result by the third number: $12 \times 2 = 24$.

Therefore, $4 \times 3 \times 2 = 24$.

To solve $8 + 3 \times 2$, follow the order of operations (PEMDAS/BODMAS):

1. First, perform the multiplication: $3 \times 2 = 6$.

2. Then, add the result to 8: $8 + 6 = 14$.

Thus, the answer is$14$.
