Answer 2

To solve the given expression, let's follow the order of operations (PEMDAS/BODMAS):

First, we perform multiplication and division from left to right: 40 × 2 = 80 6 × 4 = 24

Now, the expression becomes: 80 - 2 + 50 - 24 - 21 + 4

Next, we perform addition and subtraction from left to right: 80 - 2 = 78 78 + 50 = 128 128 - 24 = 104 104 - 21 = 83 83 + 4 = 87

Therefore, the value of the expression 40×2-2+50-6×4-21+4 is 87.
