Question

Estimate the following using general rule.
$796 - 314$

Answer 1

Hint: We’ll discuss the arithmetic and its property related to addition, subtraction, and multiplication and how they are used for the simplification here or the general method to solve the arithmetic problems, here we’ll just learn about the subtraction of two numbers. Using the arithmetic method for the subtraction of two numbers we’ll solve our problem to get the required answer.

Complete step by step answer:

Given data: $796 - 314$

Arithmetic is a branch of mathematics that deals with the numbers and its operations like addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

According to the general rule, while subtracting a number from another number, we place the ones’ place digit of the number which has to be subtracted right below the ones place digit of the number from which the subtraction is taking place, the same will go with the tenth place digit, hundredth place digit and so on.

Now we have $796 - 314$

$
   - \,\,\,\underline {\begin{array}{*{20}{c}}
  7&9&6 \\
  3&1&4
\end{array}} \\
  \,\,\,\,\,\,\underline {\begin{array}{*{20}{c}}
  4&8&2
\end{array}} \\
 $

Therefore, the value $796 - 314$ is equal to $482$

Note: In this type of question positioning is very important if we just mislocate a single-digit the answer will get an error, like if places the hundredth place digit under the tenth place digit, we’ll get the wrong answer, so remember always to place the number properly.
