Answer: 8 – (2 + 1) × (5 – 3) = 2
Step-by-step explanation:
8 – 2 + 1 × 5 – 3 = 2
8 – 2 + 1 × 5 – 3 = 2 ==> notice there is an '8-' in the equation, Let's solve for the difference between 8 and 2.
8 – (2 + 1 × 5 – 3)+(2 + 1 × 5 – 3) = 2 + (2 + 1 × 5 – 3)
8=2 + (2 + 1 × 5 – 3)
8-2=2-2+(2 + 1 × 5 – 3)
6=2 + 1 × 5 – 3 ==> 6 is a multiple of 2 and 3. Let's see how we can convert 2 + 1 × 5 – 3 into the product of 2 and 3
6=(2 + 1) × (5 – 3)
6=3 × 2
6=6√ ==> since this is right, let's substitute the parentheses to the original equation
8 – 2 + 1 × 5 – 3 = 2 ==> 8 – (2 + 1) × (5 – 3) = 2
