## How do you tell if an equation has no solution?

Summary.

If the equation ends with a false statement (ex: 0=3) then you know that there’s no solution.

If the equation ends with a true statement (ex: 2=2) then you know that there’s infinitely many solutions or all real numbers..

## Why Bodmas is wrong?

BODMAS is wrong. That’s what. … 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 comes first multiplication or adding?

If students don’t remember the rules for order of operations, remind them that multiplication and division come before addition and subtraction.

## What does the 3 mean in math?

In mathematics, the expression 3! is read as “three factorial” and is really a shorthand way to denote the multiplication of several consecutive whole numbers. Since there are many places throughout mathematics and statistics where we need to multiply numbers together, the factorial is quite useful.

## Is it 16 or 1 math problem?

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 you tell if a system of equations has no solution?

A system of linear equations has one solution when the graphs intersect at a point. No solution. A system of linear equations has no solution when the graphs are parallel.

## What are the 7 hardest math problems?

The 7 Unsolved Mathematical ProblemsPoincaré Conjecture.Birch and Swinnerton-Dyer Conjecture.Hodge Conjecture.Navier–Stokes Existence and Smoothness.P Versus NP Problem.Riemann Hypothesis.Yang-Mills Existence and Mass Gap.

## Can an equation have more than one answer?

It is possible for other equations (e.g., quadratic equations) to have more than one solution, but in terms of linear, no.

## What is the answer to the virus math problem?

The PEMDAS version of solving it gets the answer 16. But those who use a different method called BODAS — brackets, orders, division, multiplication, addition and then subtraction — get an answer of 1. For anyone who didn’t get 16 or 1 as an answer, well, it’s probably time to brush up on your math skills.

## What is the easiest math equation?

The Collatz conjecture is one of the most famous unsolved mathematical problems, because it’s so simple, you can explain it to a primary-school-aged kid, and they’ll probably be intrigued enough to try and find the answer for themselves. So here’s how it goes: pick a number, any number. If it’s even, divide it by 2.

## Who invented math?

Beginning in the 6th century BC with the Pythagoreans, the Ancient Greeks began a systematic study of mathematics as a subject in its own right with Greek mathematics. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

## What is better Bodmas or Pemdas?

PEMDAS and BODMAS both count division and multiplication as a single step. The ultimate rule is to go from left to right, so either way the answer is 9. Originally Answered: Should we follow BODMAS or PEMDAS in mathematical calculations? PEMDAS/PEDMAS is more accurate than BODMAS.

## What was the first math problem?

1650 BC – Rhind Mathematical Papyrus, copy of a lost scroll from around 1850 BC, the scribe Ahmes presents one of the first known approximate values of π at 3.16, the first attempt at squaring the circle, earliest known use of a sort of cotangent, and knowledge of solving first order linear equations.

## What is the longest math equation?

What is the longest equation in the world? According to Sciencealert, the longest math equation contains around 200 terabytes of text. Called the Boolean Pythagorean Triples problem, it was first proposed by California-based mathematician Ronald Graham, back in the 1980s.
