Question

Find the sum. $$5.7+(-9.5)+5.2$$

Short answer

1.4

Step-by-step solution

Identify the numbers

The numbers in this problem are 5.7, -9.5 and 5.2. The plus sign before the parenthesis around -9.5 indicates to add, but because the number inside the parenthesis is negative, this is equivalent to subtraction.

Add/Subtract in Order

Begin by adding 5.7 and -9.5. Remember that adding a negative number is the same as subtracting the absolute value of that number, so this becomes 5.7 - 9.5. That equals -3.8. Then, add 5.2 to the result: -3.8 + 5.2 equals 1.4.

Write the Final Answer

Having calculated all the operations, the answer to the problem 5.7 + (-9.5) + 5.2 is 1.4. Make sure to double-check your work here.
