Given the expression


(7-2)\cdot24+34-10

We must need solve what's inside ( ) first, and 7 - 2 = 5, therefore:


\begin{gathered} (7-2)\cdot24+34-10 \\ \\ 5\cdot24+34-10 \end{gathered}

Now we have a multiplication, we must do them before we do the sums and substractions, and 5 x 24 = 120:


\begin{gathered} 5\cdot24+34-10 \\ \\ 120+34-10 \end{gathered}

Now we don't have an order or priority, we can do any of them. I'll do the sum first and then subtract 10 after.


\begin{gathered} 120+34-10 \\ \\ 154-10 \\ \\ 144 \end{gathered}

Now we completely simplified the expression, and we can say that


(7-2)\cdot24+34-10=144

The order to solve a numeric expression is:

1 - Solve everything inside ( )

2 - Solve everything inside [ ]

3 - Solve everything inside { }

4 - Divide and Multiply

5 - Add and Subtract
