## How is an equation like a sentence?

An equation is a mathematical sentence containing an equals sign. It tells us that two expressions mean the same thing, or represent the same number. An equation can contain variables and constants. You can think of the letters as containers, or boxes, that can hold different numbers.

## What is the most famous equation?

Einstein’s greatest equation, E = mc2, is a triumph of the power and simplicity of fundamental physics. Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously.

## What is the hardest equation?

It’s called a Diophantine Equation, and it’s sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. On the surface, it seems easy.

## What are the parts of an equation?

Expressions can consist of one or more of these components: numerical constants, symbolic names, mathematical operators, functions, and conditional expressions.

## Is an equation a formula?

equation: A statement formed by placing an equals sign between two numerical or variable expressions. formula: An equation that states a rule about a relationship.

## What do you call a multiplication equation?

Multiplier is the number that tells how many times a multiplicand should be multiplied. The multiplicand and the multiplier are also called factors. The multiplier is often written first, but the position of these numbers does not really matter. The answer in a multiplication equation is called the product.

## What are the names of a multiplication problem?

The numbers to be multiplied are generally called the “factors”. The number to be multiplied is the “multiplicand”, and the number by which it is multiplied is the “multiplier”.

## What are the parts of a math problem called?

All parts of arithmetic equations have names. In an addition equation, addends are the numbers that are added together to give a sum. In a subtraction equation, the subtrahend is taken away from the minuend to give a difference. In a multiplication equation, factors are multiplied to give a product.

## What is multiplication of numbers?

Multiplication is when you take one number and add it together a number of times. Example: 5 multiplied by 4 = 5 + 5 + 5 + 5 = 20. We took the number 5 and added it together 4 times. This is why multiplication is sometimes called “times”.

## Why are times tables so important?

Knowing the times tables (and their associated division facts) supports mathematical learning and understanding and those children who have a strong grasp of them tend to be more self-assured when learning new concepts.

## Why do we learn tables?

They help with mental arithmetic. Memorising times tables makes it far quicker and easier for children to work out maths problems in their heads. Moving beyond using their fingers to work out answers, they’ll gradually be able to use their knowledge to quickly solve any multiplication questions.

## How many times tables should you learn?

We recommend that you start off by learning the 2 times table. The 2 times table makes a fantastic foundation-block for learning other tables and will come in handy in maths more generally. For example, your child will soon realise that multiplying by 2 is the same as doubling!

## Why do we learn times tables up to 12?

MULTIPLICATION tables do not end at 12, they are infinite, but we only learn them up to 12 because they are difficult, we have calculators and as there used to be 12 pence in a shilling this was the most useful number for everyday ready reckoning at the grocer’s shop.

## Who invented times tables?

ancient Babylonians
