Well, out here on the East Coast (NYC) it is...
No it is BODMAS.

So, with BOMDAS how would you solve this if you don't have the "E" for Exponent? I am not down playing the BOMDAS method. I am just asking.

52 x 10=
BTW where you from Kefta? I like learning new things from people in different states.
look at this way:
(1+1+1+1+1+1+1+1+1+1+1+1) × (0+1) =
12 x 1 = 12
(1+1+1+1+1+1+1+1+1+1+1+1) × (0+1) =
12 x 1 = 12
Anything multiplied by 0=0
So the only answer is 1... Why do I keep seeing other answers
different countries. I don't think they have BODMAS in America. They do in British influenced countries.
B - Brackets (or as the USA calls it, parenthesis)
O - Order (or as the USA calls it, Exponent. Other countries call it Index)
D - Division
M - Multiplication
A - Addition
S - Subtraction
Keep in mind, it doesn't matter if you multiply or divide first, so in the order of operations, when working from left to right you can either divide or multiply first. PEMDAS or PEDMAS is the same thing.
How did you arrive with 1?
7-4+3×0+1=4
Why?
Using PEMDAS,
7-4+(3×0)+1
7-4+0+1
3+0+1
3+1
4
So if there are no parenthesis in the equation, you just automatically place them in there? And apply that method. It's been over twenty years since I learned this formula.
I placed the parentheses in for emphasis when solving the equation.
You have to multiply or divide before adding and subtracting. If there was a parenthesis or bracket in the equation, then you solve that first, then exponents, then multiply or divide then add or subtract. My answer is the same as a calculator's answer.
As for doing math in a minute, I am in the same boat as you. I am no math wiz, but I do understand order of operations.
I guess the point of this thread is that lately, these types of equations have been popping up in my Facebook timeline lately and I don't understand why.
I do find it interesting that these equations create a lot of responses from people around the world w/ occassional debates on how to solve it. The latest equation darn near is approaching 900K responses!! That's crazy to me. Lol
Simple. Facebook is one big ass data/information collection website. Every unique response to these types of questions creates a treasure trove of data that can be used for global comparison ("Australians are ____ more likely to know the correct answer to XYZ equation than their Canadians counterparts), marketing ("Someone in your family struggles with math. Let XYZ Software/Tutoring help them get on par with their US/Mexican/Germany counterparts in their age range), etc.
Other than being a centralized attention whoring database, FB real value is the kind of data it can collect and sell with out people realizing every "like" or answer is them being watched behind the online mirror-glass.
Ok. So, basically it is done for marketing purposes, right?
Thanks!!!!!!
