20-2×8+66

To solve the expression \(20 - 2 \times 8 + 66\), follow the order of operations (PEMDAS/BODMAS):

1. First, perform the multiplication: \(2 \times 8 = 16\)

2. Now, substitute that back into the expression: \(20 - 16 + 66\)

3. Next, perform the subtraction: \(20 - 16 = 4\)

4. Finally, add: \(4 + 66 = 70\)

So, the result of the expression \(20 - 2 \times 8 + 66\) is \(70\).
