Dollars or cents
what is the question
Answer:
8 - (3 x 2) - (1 + 1) = 0
or
8 - 3 x 2 - (1 + 1) = 0
Remember PEMDAS.
If I put parenthesis around 3 x 2, I get 6.
But 8 - 6 = 2
How can we make 2 - 1 + 1 = 0?
If we look at PEMDAS, we know (2 - 1) + 1 = 2, but the answer needs to be 0.
So now try 2 - (1 + 1) and that gives me 0.
And it says parentheses...but you can also do 8 - 3 x 2 - (1 + 1) = 0.
If the figure is drawn in a 2/5 scale, this means that all the length will be multiplied by 2/5. The area is a two-dimensional thing, so it would be multiplied by that factor twice, or 4/25. You can try checking all the lengths. The correct one should match all of the things I said above.
The answer is the top left one.
