Let's break down the expression step by step:

2 + 5 + 90 ÷ 2 × 45 - 150 ÷ 3

First, we perform the division and multiplication operations from left to right:

2 + 5 + 45 × 45 - 50

Next, we perform the multiplication operation:

2 + 5 + 2025 - 50

Now, we perform the addition and subtraction operations from left to right:

7 + 2025 - 50

Finally, we perform the remaining addition and subtraction:

2032 - 50

The final result is:
