It seems people can’t help but reminisce to days spent sweating their way through a maths class on standard deviation and simultaneous equations.
Ahh the good times.
A ‘simple’ maths equation has resurfaced online:
And once more, people are a little confused.
Dispute seems to be between two answers - 50 and 56:
Here's how we worked it out:
Method 1
7+7=14
14/7=2
2+7=9
9X7=63
63-7=56
With this method, the answer is 56.
This is wrong in some people's eyes, because it doesn't follow the order of operations, or BODMAS.
Method 2
Therefore following the rules of BODMAS, we have to divide, then multiply, and finally add and subtract.
7+(7/7)+(7X7)-7
7+1=8
7X7=49
8+49=57
57-7=50
The answer, according to BODMAS (and the majority of people on Facebook) is 50.
