Find and explain the error.    
 5 - 3 + 2
     5 - 5
        0

• There is no error.

• Addition was done first and you should have subtracted first

• There is a subtraction error

Find the Error

 $\left(5^2+\ 5\right)\ \div-3$  
 $\left(10+5\right)\div\ -3$  
 $15\ \div-3$  
 $-5$  

• Step 1 to Step 2

• Step 2 to Step 3

• Step 3 to Step 4

• No error 

 $7\left(10\div-5\right)-\left(-5\right)$  

• 19

• -19
