Multiplication and division - Examples, Exercises and Solutions

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

$10\cdot2=20$

$20/4=5$

To solve $10-4 \div 2$, we follow the order of operations (PEMDAS/BODMAS): Parentheses or Brackets, Exponents or Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

First, perform the division: $4 \div 2 = 2$.

Next, substitute back into the expression: $10 - 2 = 8$.

Therefore, the correct answer is $8$.

To solve $10 \div 2 + 1$, follow the order of operations:

1. First, perform the division: $10 \div 2 = 5$.
2. Then, add 1 to the result: $5 + 1 = 6$.

Thus, the answer is 6.

To solve the expression $10\div2-4=$, follow the order of operations, which prioritizes division over addition.

1. Divide $10$ by $2$ to get $5$.

2. subtract $4$ from $5$: $5-4 = 1$.

First, perform the division: $10 \div 2 = 5$.

Next, divide the result by 1: $2 \div 1 = 2$.

So, the answer is $2$.

To solve $10 \div 5 \times 6$, you need to follow the order of operations: first perform the division and then the multiplication.

Step 1: Divide 10 by 5: $10 \div 5 = 2$

Step 2: Multiply the result by 6: $2 \times 6 = 12$

So, the answer is $12$.

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

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, 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: $4 \times 3 = 12$.

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

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

To solve 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, perform the multiplication operation:

$5 \times 2 = 10$

Then add 1 to the result:

$10 + 1 = 11$

Therefore, the correct answer is:

$11$

First, perform the division:

$6 / 2 = 3$

Then add 5:

$3 + 5 = 8$
