1. **Find the value of 5 + 2.**

Show me the answers!

**Correct answer is option - 3**

**Explanation:**

By the method of general addition, 5 + 2 = 7.

So the answer is 7.

2. **What is the value of 5 + 3 + 4?**

Show me the answers!

**Correct answer is option - 1**

**Explanation: a**

By the general method of addition, we start from the left and get 5 + 3 = 8 and then 8 + 4 = 12.

So the answer is 12.

3. **The value of 6 – 5 is?**

Show me the answers!

**Correct answer is option - 1**

**Explanation:**

By the general method of subtraction, we start from the left and get 6 – 5 = 1.

So the answer is 1.

4. **What is the value of 4 – 7?**

Show me the answers!

**Correct answer is option - 2**

**Explanation:**

In the given integers, ‘4’ is a positive number and ‘7’ is a negative number. Since there is at least one negative sign we subtract.

But after subtracting, the final answer gets the sign of the bigger number.

This gives: 4 – 7 = -3.

5. **What is the value of -5 – 10?**

Show me the answers!

**Correct answer is option - 4**

**Explanation:**

Here in the question, since both the numbers have negative signs, hence we add the numbers but the final answer gets a negative sign as well!

This implies: -5 – 10 = -15.

6. **What is the value of -7 + 4 – 2?**

Show me the answers!

**Correct answer is option - 5**

**Explanation:**

Here it’s safe to go step-by-step by starting from the left side.

So we get: -7 + 4 = -3. Now, -3 – 2 = -5.

So the final answer is -5.

7. **What is the value of 2x + 4x?**

Show me the answers!

**Correct answer is option - 3**

**Explanation:**

Since both the terms, ‘2x’ and ‘4x’ contain ‘x’ as the variable hence they are like terms and can be added directly like general integers.

So 2x + 4x = (2 + 4) x = 6x.

8. **Evaluate: 6x + 7x + 3x**

Show me the answers!

**Correct answer is option - 4**

**Explanation:**

Since here all the terms contain ‘x’ as the variable, hence they are like terms and can be added directly.

This gives: 6x + 7x + 3x = (6 + 7 + 3) x = 16x.
