Question

Simplify the expression. (7 − 2)24 + 34 − 10

Answer 1

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
