We want to simplify the mathematical expression;
2(10 - 6)² + 3*4
The correct steps are as follows;
Step 1; Using BODMAS Acronym, let us deal with the bracket first to get;
2(4)² + 3*4
Step 2; Still dealing with the bracket, we will now have;
2(16) + 3*4
Step 3; Still dealing with the bracket, we will now have; 32 + 3*4
Step 4; Next sign to be used is multiplication sign and as such we now have; 32 + 12
Step 5; Using the addition sign, we now have 44
Thus, where the friend made the error was in step 2. She should have squared the 4 first before multiplying by 2.
