Is 6 2 1 2 1 or 9?

The answer to the expression 6 ÷ 2(1 + 2) is 9 according to modern mathematical conventions. The expression is widely considered ambiguous due to a lack of clear notation, leading to the two different results.

Why is 6 2 1 2 )= 9 not 1?

there is no "correct" order. the conventional rules don't rule out either 1 or 9. this expression could be interpreted both as 6/(2(1+2)) which gives 1 or (6/2)(1+2) which gives 9.

Does 6 2 1 2 equal 1 or 9?

This gets to the correct answer of 9. This is without argument the correct answer of how to evaluate this expression according to current usage. Some people have a different interpretation.

What are common PEMDAS mistakes?

Common Mistakes When Using PEMDAS

Forgetting Left-to-Right Rule: Multiplication and division, as well as addition and subtraction, must be performed in order from left to right. ❌ Wrong: 30 ÷ 5 × 3 = 30 ÷ 15 = 2.

How do you say "I love you" in math?

You can say "I love you" in math through number codes like 143 (I-love-you, based on letter count) or 520, by graphing equations that form a heart shape (like using inequalities), or with fun calculator tricks using specific functions to display letters. You can also use mathematical concepts like the Golden Ratio (1.618) to represent universal beauty or create algebraic puzzles where solving for 'I' reveals "I heart you".
 

6÷2(1+2) = ? Correct Answer Explained By Mathematician

Is it Pemdas or BODMAS answer?

BODMAS is an acronym and it stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction. In certain regions, PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction) is used, which is the synonym of BODMAS.

Is the BODMAS rule correct?

There may be times when solving simultaneous equations where it is easier to collect like terms first. Therefore you would do addition before multiplication, however, when it comes to solving the equation you would still use BODMAS. That is always the correct order to solve an equation.

What defines a "correct" answer?

A 'correct answer' is defined as a response that accurately reflects the right solution to a question, contributing to the total score in a testing scenario, as exemplified by the calculation of maximum possible correct answers in a group of questions.

What is the toughest maths question in the world?

There's no single "hardest" math question, but top contenders for unsolved problems include the Riemann Hypothesis (prime number distribution), P vs NP (computation complexity), and the Navier-Stokes existence and smoothness (fluid dynamics), all with significant prizes and profound implications, alongside deceptively simple-sounding problems like the Collatz Conjecture and Goldbach's Conjecture that remain unproven.
 

Why doesn't PEMDAS always work?

PEMDAS is shortsighted. It ignores mathematical properties (that is, laws), which take precedence over order of operations like PEMDAS (an accepted convention, not a law or property).

Why is 9 repeating 1?

0.999... is a repeating decimal that is an alternative way of writing the number 1. The three dots represent an infinite list of "9" digits.

What is the only number you cannot divide by?

0 Divided by a Number 0a=0 Dividing 0 by any number gives us a zero. Zero will never change when multiplying or dividing any number by it. Finally, probably the most important rule is: a0 is undefined You cannot divide a number by zero!

Is PEMDAS right or wrong?

Yes, PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) is a widely used and helpful mnemonic for the order of operations in math, but it's a simplification; the key is that Multiplication/Division have equal priority (left-to-right), and Addition/Subtraction have equal priority (left-to-right), which sometimes confuses students into doing all M before all D, or all A before all S. It ensures consistent answers for expressions, but for true clarity in complex math, using brackets to explicitly group operations is better than relying solely on PEMDAS.
 

Do I divide first or multiply first?

Applying the Order of Operations (PEMDAS)

The order of operations says that operations must be done in the following order: parentheses, exponents, multiplication, division, addition, and subtraction.

Which is more accurate, PEMDAS or BEDMAS?

The question of whether it's "PEMDAS or BEDMAS" or "is it PEDMAS or PEMDAS" often arises, but the truth is that these are simply different ways of expressing the same concept. PEMDAS stands for Parentheses, Exponents, Multiplication, and Division, Addition, Subtraction (from left to right).

What is 1 ➗ 0 and why?

1 divided by 0 (1/0) is undefined in standard mathematics because it breaks the rules of arithmetic; it doesn't equal a number like infinity (though limits approach infinity) and leads to contradictions, as you can't group things into zero-sized groups to make one. Division is repeated subtraction or grouping, and asking "how many zeros make one" has no answer, as adding zero always gives zero, never one.
 

What math says "I love you"?

The number 371 has become popularized as a shorthand way to say “I love you” in the language of mathematics and numeric codes.

How is 143 equal to "I love you"?

The number 143 means "I love you" because it represents the letter count of each word: "I" (1 letter), "love" (4 letters), and "you" (3 letters). This shorthand became popular in the 1990s with pagers and text messages, where brevity was essential, and is also linked to a famous lighthouse known as the "I Love You lighthouse".
