The correct Answer is:
To determine who has the correct answer among Seema, Anees, Asha, and Tessy, we will evaluate each expression step by step using the order of operations (often remembered by the acronym PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). ### Step-by-Step Solution 1. **Evaluate Seema's Expression:** - Expression: \(4 \times 1 + 8 + 2\) - Step 1: Perform multiplication first. \[ 4 \times 1 = 4 \] - Step 2: Now add the results. \[ 4 + 8 + 2 = 14 \] - Conclusion: Seema's answer is \(14\), which does not equal \(8\). **Seema is incorrect.** 2. **Evaluate Anees's Expression:** - Expression: \(6 + 4 + 2 - 8\) - Step 1: Perform addition from left to right. \[ 6 + 4 = 10 \] - Step 2: Continue adding. \[ 10 + 2 = 12 \] - Step 3: Now subtract. \[ 12 - 8 = 4 \] - Conclusion: Anees's answer is \(4\), which equals \(4\). **Anees is correct.** 3. **Evaluate Asha's Expression:** - Expression: \(9 + 3 \times 2 - 4 + 2\) - Step 1: Perform multiplication first. \[ 3 \times 2 = 6 \] - Step 2: Substitute back into the expression. \[ 9 + 6 - 4 + 2 \] - Step 3: Perform addition and subtraction from left to right. \[ 9 + 6 = 15 \] \[ 15 - 4 = 11 \] \[ 11 + 2 = 13 \] - Conclusion: Asha's answer is \(13\), which does not equal \(10\). **Asha is incorrect.** 4. **Evaluate Tessy's Expression:** - Expression: \(27 + 3 - 2 \times 3\) - Step 1: Perform multiplication first. \[ 2 \times 3 = 6 \] - Step 2: Substitute back into the expression. \[ 27 + 3 - 6 \] - Step 3: Perform addition and subtraction from left to right. \[ 27 + 3 = 30 \] \[ 30 - 6 = 24 \] - Conclusion: Tessy's answer is \(24\), which does not equal \(12\). **Tessy is incorrect.** ### Final Conclusion: The only person who has the correct answer is **Anees**.
