Addition and subtraction - Examples, Exercises and Solutions

According to the rules of the order of arithmetic operations, we will work to solve the exercise from left to right:

9+3=11

11-1=10

And this is the solution!

According to the rules of the order of operations, given that the exercise only involves subtraction and addition operations, we solve the exercise from left to right:

$3+2=5$

$5-1=4$

Add first: $6 + 5 = 11$.

Then, subtract: $11 - 8 = 3$.

The correct answer is $3$.

First, add 5 and 9 to get 14.

$5 + 9 = 14$

Then, subtract 3 from 14 to get 11.

$14 - 3 = 11$

First, add 7 and 5 to get 12.

$7 + 5 = 12$

Then, subtract 2 from 12 to get 10.

$12 - 2 = 10$

First, subtract 4 from 15 to get 11.

$15 - 4 = 11$

Then, add 3 to 11 to get 14.

$11 + 3 = 14$

First, subtract 6 from 8 to get 2.

$8 - 6 = 2$

Then, add 4 to 2 to get 6.

$2 + 4 = 6$

First, subtract the second number from the first:

$12 - 5 = 7$

Then, subtract the third number from the result:

$7 - 2 = 5$

So, $12 - 5 - 2 = 5$

First, we perform the addition: $7 + 2 = 9$.

Next, we do the subtraction: $9 - 4 = 5$.

Hence, the answer is $5$.

Perform the addition operation first:

$4 + 8 = 12$

Then subtract 5 from the result:

$12 - 5 = 7$

Therefore, the correct answer is:

7

Solve the additions and subtractions from left to right:

$8 - 2 = 6$

Then add 6:

$6 + 6 = 12$

Start by adding: $10 + 1 = 11$.

Finally, subtract: $11 - 7 = 4$.

The solution is $4$.

Start with the initial expression: $10 - 3 - 1$.

First, subtract 3 from 10: $10 - 3 = 7$.

Next, subtract 1 from the result: $7 - 1 = 6$.

Therefore, the final answer is $6$.

To solve $10+5-3$ follow these steps:

1. $10 + 5 = 15$

2. $15 - 3 = 12$

So the answer is $12$.

To solve $15 - 4 - 3$, follow these steps:

1. First, subtract 4 from 15: $15 - 4 = 11$.

2. Next, subtract 3 from the result: $11 - 3 = 8$.

3. Therefore, the correct answer is $8$.
