Alex has a number game - OCR - GCSE Maths - Question 3 - 2020 - Paper 3

To determine if Alex is correct, we need to evaluate both sides of the equation:

1. For the left side:

   $2 - 3 \times 2$

   Here, we must follow the order of operations (PEMDAS/BODMAS), which stipulates that we perform multiplication before subtraction:

   $2 - 6 = -4$

2. For the right side:

   $3 - 5 = -2$

Now, we compare the results:

• The left side equals -4.
• The right side equals -2.

Since -4 does not equal -2, Alex's calculations are incorrect.

Thus, Alex is incorrect because the two calculations do not yield the same result.
