Abott make his first mistake in step 2Further explanation Calculation operations include multiply, divide, add, substract, etc. In mathematical operations we can use the order of operation / calculation according to the principle of PEMDAS P: Parentheses ⇒ ( ) E: Exponents (powers, square roots, etc.)⇒√,² MD: Multiplication and Division ⇒ x and : AS: Addition and Subtraction ⇒ + and - Multiplication and division or addition and subtraction are interchangeable/rank equally so the calculations/equation operations should be done from left to right Abbot expression :9.5 : 0.25 + + 4(0.25+0.5) + 6Step 1 : 9.5 : 0.25 + + 4(0.75) + 6Step 2 : 38 + 10(0.75)Step 3 : 38 + 7.5Step 4 : 45.5From the Abott steps it can be concluded that the error occurred in step 2, because the number 4 must be multiplied first with the number in parentheses (ie 0.75)The correct steps should: step 1: Step 1: 9.5: 0.25 + 4 (0.75) + 6 Step 2: 38 + 3 + 6 Step 3: 38 + 9 Step 4: 47Learn morePEMDAS : PEMDAS, an expression, Abott, step, mistake#LearnWithBrainly
