What is the correct answer to 2 2×4?
The answer for 2+2×4 = 10. I followed PEMDAS to solve this problem. i.e. Parentheses Exponential Multiplication Division Addition Subtraction.
How is 2 2×4 equal 10?
Apparently 2+2×4=10 because you always x before + This is news to me. The way I was taught, sums are read left to right unless ( ) tell you to do that bit first. So for 10 the sum should be 2+(2×4)=10 Otherwise 2+2=4 then 4×4=16 Have I been doing it wrong for 45 years? BODMAS system innit?
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.
How do I solve this problem?
8 steps to problem solving

- Set some goals.
- Brainstorm possible solutions.
- Rule out any obvious poor options.
- Examine the consequences.
- Identify the best solutions.
- Put your solutions into practice.
- How did it go?
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 Bedmas apply when there are no brackets?
Just follow the rules of BODMAS to get the correct answer. There are no brackets or orders so start with division and multiplication. 7 ÷ 7 = 1 and 7 × 7 = 49.
Is Bodmas and Pemdas the same?
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.
Why Bodmas is wrong?
Wrong answer Its letters stand for Brackets, Order (meaning powers), Division, Multiplication, Addition, Subtraction. It contains no brackets, powers, division, or multiplication so we’ll follow BODMAS and do the addition followed by the subtraction: This is erroneous.
What are the 7 hardest math problems?
The problems are the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Poincaré conjecture, Riemann hypothesis, and Yang–Mills existence and mass gap.
How do you identify problems and solutions?
Here are seven-steps for an effective problem-solving process.
- Identify the issues. Be clear about what the problem is.
- Understand everyone’s interests.
- List the possible solutions (options)
- Evaluate the options.
- Select an option or options.
- Document the agreement(s).
- Agree on contingencies, monitoring, and evaluation.
What is 2 out of 3 as a percentage?
66%
Convert 2/3 to a per cent. Therefore, the solution is 66%.
