Can there be more than one answer to a math problem?
Yes, there can be two different right answers on a math problem. Math problems are not always of the kind “find all possible solutions” as in “find all numbers that multiplied by themselves make 4”. A math problem can also be “find a number that multiplied by itself makes 4” for instance.
Is it 1 or 16?
Some people got 16 as the answer, and some people got 1. The confusion has to do with the difference between modern and historic interpretations of the order of operations. The correct answer today is 16. An answer of 1 would have been correct 100 years ago.
Is Pemdas or Bodmas correct?
BODMAS stands for Brackets, Orders, Division, Multiplication, Addition and Subtraction. BIDMAS and PEMDAS do exactly the same thing but using different words. BODMAS explains the “Order of Operations” in maths and BIDMAS AND PEMDAS do exactly the same thing but using slightly different words.
What is an example of quantitative reasoning?
It looks like, on average, each resident of the city buys 1.6 pounds of candy per year. The mayor decides that this makes sense based on the facts of the problem, so he has his answer. The reasoning that the mayor used in this scenario is an example of using quantitative reasoning to solve a real-world problem.
Why do calculators give different answers?
But how come one calculator of the same brand said that the answer is 1? The difference has something to do with the mode or the program of the calculator. For one, not all calculators follow the order-of-operations hierarchy, which leads to a different interpretation of the equation.
What does 2/3rds mean?
Two-thirds of something is an amount that is two out of three equal parts of it. American English: two-thirds /ˌtuˈθɜrdz/ Brazilian Portuguese: dois terços.
Does multiplication always come first?
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Next, add and subtract from left to right. (Note that addition is not necessarily performed before subtraction.)

Do calculators use Bodmas?
BODMAS or BIDMAS must also be used when using a calculator. Scientific calculators automatically apply the operations in the correct order, however extra brackets may be required.
