first you mark me brilliant plz plz

Answer 2

Step-by-step explanation:

The answer is ‘1’, not ambiguous due to PEMDAS.

The reason why people create the error ‘16’ is two things:

Computers perform the first operation inline, such as XYZ rather than (XYZ) which means Z suddenly exists as a third step rather than evaluated as a whole. This means in the case X/YZ, you have X/Y possibly done first, then multiplied with Z. This is obviously wrong if that’s not your intent! X/YZ following PEMDAS rules means basically X/(YZ), you always multiply the Y and Z first. Any machine doing instructions inline like this you need to state explicitly what you want done first using parentheses. Thus this equation 8/2(2+2) on paper is always 8/8=1. It’s 16 if you break the rule or enter it improperly which is an error based on the intent. The steps of doing 8/2 first could happen based on complete misinterpretation error, or ‘instruction optimization’ which is the second reason below.

Division can turn to quick-tricks such as bitwise division and integer multiplication, so thus this equation in machine code becomes 8*0.5*(2+2) = 16 or already ‘16’ which is an error.

8÷2(2+2) by itself is not following the universal PEMDAS rule if it performs the 8 divided by 2 operation first. It’s following linear instruction (left to right,no rules), or an unknown ruleset explicitly dividing before multiplying which is erroneous.

Solution: on any CPU or language use 8/(2(2+2)) or 2(2+2)/8 to ensure the correct answer of ‘1’. Use 8*0.5*(2+2) or (8/2)(2+2) exclusively to get ‘16’. To ensure randomness, simply guess if it will divide before multiplying, as it doesn’t follow PEMDAS unless you explicitly tell it to.

Sad if universities/students don’t follow their own rules. In any case you don’t want one when it should be the other in a real case scenario. It’s mostly a language or human interpretation error.

ps: It’s clearly a language and order of operations question, if you wrote this equation on paper for highschool or above while teaching PEMDAS it’s ‘1’ and I’d know any ‘16’ was using calculators, and not realizing 8 divided by 2 is not right without saying it or writing something like ‘16’ or ‘1’. They entered the numbers and didn’t think. Entering properly to a calculator is part of basic math, it’s not ‘16’ if a person failed to enter it. PEMDAS is crucial for having the same result in algebra and higher and that’s why every person who learned math up to 10+ years to centuries ago who encountered something like this on paper would instantly say it’s ‘1’. Brainless calculator typing and euro-tricked bodmas students say it’s ‘16’ if they don’t understand or tricked to do other made up orders. The ones introducing the problems are at fault here.
