Answer 1

To solve the problem 2.75 + (-2) + 5.25, you add the positive numbers (2.75 + 5.25) to get 8, then add the negative number, which is the same as subtracting its absolute value, resulting in 6.

Step-by-step explanation:

To work out the math problem 2.75 + (-2) + 5.25, you need to follow the rules of addition for numbers with different signs.

• First, add the positive numbers together (2.75 + 5.25) which equals 8.
• Next, add the negative number to this result. Since adding a negative number is the same as subtracting its absolute value, you have the equivalent operation of 8 + (-2).
• Now, following the rule that when two numbers with opposite signs are added, you subtract the smaller number from the larger number and take the sign of the larger number, you get 8 - 2, which equals 6.

So, the answer to the problem 2.75 + (-2) + 5.25 is 6.
