Introduction to elementary math estimation:
In elementary number theory, integers are studied without use of techniques from other mathematical fields. Questions of divisibility, use of the Euclidean algorithm to compute greatest common divisors, integer factorizations into prime numbers, investigation of perfect numbers and congruence’s belong here. Several important discoveries of this field are Fermat's little theorem, Euler's theorem, the Chinese remainder theorem and the law of quadratic reciprocity. (Source: Wikipedia)
Types of Elementary Math Estimation:
There are four types of basic theory are mainly used in the elementary number theory; these types are classified according to the representation of the number. It will be shown as below,
Addition
Subtraction
Multiplying
Division
In elementary math to estimation it very easy to learning to study. And solve it easy. There are four steps are used in the elementary estimation of the math problems they are solved in the example problems in given below.
Example Problem for Elementary Math
Example 1:
Estimation the example of adding two numbers 163 and 13
Solution:
Let us write the given problem as 163 + 13.
Add the number 163 and 13 we get the sum as,
163 + 13 =176
Therefore, the solution for adding 163 + 13 is 176.
Example 2:
There are 56 peoples travelling in a bus. 17 of them left from the bus in one stopping. Estimation how many people will be left in the bus?
Solution:
Total number of peoples = 56
Number of peoples left from the bus in one stopping = 17
Number of peoples left in the bus = 56 - 17
= 39
Example 3
Estimation the multiplying two numbers 31 and 27
Solution:
The given two numbers 31 and 27
We need to find the product of two numbers
By multiplying 31 and 27
We get 837
So the answer is 837
Problem 4:
Estimation to divide 400 / 4
Solution:
100(quotient)
----
4) 400
400 -
---------
0(remainder)
---------
Practice Example Problem for Elementary Math
1. Estimation of adding 33 and 70
Key: 103
2. Estimation of Subtract 119 and 9
Key: 110
3. Estimation of Multiplying 29 by 20
Key: 580
4. Estimation of Divided 68 by 7
Key: 9.71
