In evaluating the expression one third left parenthesis negative 3 right parenthesis plus 14 1 3(−3)+14​, Jenny found the value to be 15. She thinks that the number is too​ great, but is not sure what she did wrong. Evaluate the expression. Then find Jenny​'s likely error.

1/3 (-3)    + 14   =   -1  +  14 =   13

 

Likely , she did this part incorrectly:  1/3 (-3)   and got  '1'  instead of ' -1'    .....
