What is the value of 25.25 – 23.23 + 24.24_________?
Show answer Hide answer
Answer: B. 26.26
Explanation
Subtracting 23.23 from 25.25 first yields an intermediate positive difference of exactly 2.02. Adding the remaining value of 24.24 to this intermediate result produces a final sum of 26.26. Performing the decimal arithmetic directly in sequence confirms the accuracy of the final calculated value. Decimal addition and subtraction require careful alignment of decimal points to ensure correct place value operations. Basic arithmetic expressions are evaluated from left to right when operators share the same precedence level. Positive and negative decimal numbers combine according standard rules of real number arithmetic.
Financial transactions and accounting ledgers rely heavily on precise decimal addition and subtraction. Daily budgeting requires accurate calculation of monetary values involving dollars and cents. This fundamental arithmetic skill is essential for verifying bills, invoices, and computational spreadsheets. Option A rounds the decimal result incorrectly to a whole number, ignoring the fractional components. Option C results from a misplaced decimal point during the intermediate subtraction step. Option D arises from an incorrect sign error that reverses the positive and negative operations.
