## How do you check your answer in addition?

The method works like this: For any addition or multiplication problem, take the digits of each number you’re adding or multiplying and add them together. So for instance, if we were adding 218 and 435, we would add 2+1+8=11, and 4+3+5=12. Then, if we get a two-digit answer we’d repeat the process. So, 1+1=2 and 1+2=3.

## How do you know if your math answer is reasonable?

To be reasonable means to be as much as is appropriate or fair. In math, reasonableness can be defined as checking to verify that the result of the solution or the calculation of the problem is correct or not, be either estimating or by plugging in your result to check it.

## What is the check called in math?

√ is the symbol for square root. A square root is the number that, when multiplied by itself, gives the original number. For example, the square root of 4 is 2, because 2 x 2 = 4. The square root of 9 is 3, because 3 x 3 = 9.

## What is the answer for multiplication called?

When we multiply two numbers, the answer we get is called ‘product’. The number of objects in each group is called ‘multiplicand,’ and the number of such equal groups is called ‘multiplier’.

## What is the quotient of 5 12 and 3 8?

512 ÷ 38 is 109.

## What is a mixed number?

What is a mixed number? A mixed number is a number consisting of a whole number and a proper fraction.

## What is a fraction math is fun?

A Fraction (such as ^{3}/_{8}) has two numbers: NumeratorDenominator. The top number is the Numerator, it is the number of parts you have. The bottom number is the Denominator, it is the number of parts the whole is divided into.

## Can answer be incorrect even if it looks reasonable?

Explanation: Yes, an answer can be incorrect even if it looks reasonable, for two main reasons: The assumptions (premises or statements) on which the reasoning is based are wrong.
