40 × 2 - 90 ÷ 30 - 32 ÷ 10

Let's solve the expression step-by-step:

1. First, do the multiplications and divisions from left to right:

   • \( 40 × 2 = 80 \)
   • \( 90 ÷ 30 = 3 \)
   • \( 32 ÷ 10 = 3.2 \)

2. Now substitute these values back into the expression: \[ 80 - 3 - 3.2 \]

3. Now, perform the subtractions:

   • \( 80 - 3 = 77 \)
   • \( 77 - 3.2 = 73.8 \)

So, the final result is: \[ 73.8 \]
