Hint: Find the sum of – 1032 and 878 by adding them together. Then subtract the resulting number from – 34 to determine the final answer.
Complete step-by-step answer: Addition and subtraction are two basic arithmetic operators. The addition of two numbers is obtained by adding those numbers together. It is also called the sum of the numbers. The subtraction of two numbers is obtained by removing the amount of the second number from the first number. It is also called the difference between the two numbers. We need to find the sum of – 1032 and 878 and subtract the result from – 32. We first add the numbers – 1032 and 878 to obtain their sum. When the bigger number is negative and the other number is positive, then the sum is calculated by subtracting the bigger number from the smaller number and then assigning a minus sign to the result. Hence, we have: \[ - 1032 + 878 = - (1032 - 878)\] \[ - 1032 + 878 = - 154\] Next, we need to subtract – 154 from – 34. To subtract one negative number from another, we convert the second number into a positive number and then add both numbers. \[- 34 - ( - 154) = - 34 + 154\] This sum is nothing but 34 subtracted from 154, hence, we have: \[- 34 - ( - 154) = 154 - 34\] \[- 34 - ( - 154) = 120\] Hence, the final answer is 120.
Note: There are three numbers and two operations involved, so you might get confused and proceed in any possible direction. Hence, solve step by step to increase the chance of getting the correct answer.
