Answer:
On the second step there is a mistake. You have to multiply 2 times 2 before you add the five
Answer:
See below;
Step-by-step explanation:
We are given the following;
5 + [ 2 * 2 + 5 ], ⇒ add 2 and 5
5 + [ 2 * 7 ], ⇒ multiply 2 by 7
5 + 14, ⇒ combine like terms
Solution; 19
Now as we can see from the first ⇒ second step the process as to simplify the expression 5 + [ 2 * 2 + 5 ] further, was by adding 2 and 5. Of course by PEDMAS, it would be that multiplication takes place before that of addition, so that it should have been that 2 was multiplied by 2 first!
