Question

1+1-2×4÷6-25$1 + 1 - 2 \times 4 \div 6 - 25$please help me

Answer 1

The first step to solve the expression is to calculate first the products and divisions.

So first we need to calculate 2x4, and then the result we divide by 6:

$\begin{gathered} 1+1-2\cdot4\text{ / 6 - 25} \\ 1+1-8\text{ / 6 - 25} \\ 1+1-\frac{4}{3}-25 \end{gathered}$

Now that we have only sums and subtractions, we can solve the remaining operations:

$\begin{gathered} 1+1-\frac{4}{3}-25 \\ 2-\frac{4}{3}-25 \\ -23-\frac{4}{3} \\ \frac{-69-4}{3} \\ \frac{-73}{3} \end{gathered}$

So the final value of the expression is -73/3
