Introduction to 5th grade math functions:
The mathematical concept of a function expresses the intuitive idea that one quantity (the argument of the function, also known as the input) completely determines another quantity (the value, or the output). A function assigns a unique value to each input of a specified type. The argument and the value may be real numbers. (Source: Wikipedia)

5th grade math functions - Example problems:
Here we will discuss about the 5th grade math functions,
5th grade math function - Example problem: 1
Find the simple interest on a sum of Rs. 5000 for 5 years at the rate of 14% per annual.
Solution:
The given principal amount = Rs. 5000
Interest rate = 14% per annual.
Interest on Rs. 100 for 1 year = Rs. 50
Interest on Rs.2500 for 1 year = Rs. 500
Therefore,
Interest on Rs. 2500 for 3 year = 5 * 500
= Rs. 2500
[Answer: The Simple interest value is Rs. 2500]
5th grade math function - Example problem: 2
Write the given number 9564 in expanded form.
Solution:
The given number is 9564
It can be written as,
9564 = 9000 + 500 + 60 + 4
Rearrange the above numbers as,
9564 = (9 * 1000) + (5 * 100) + (6 * 10) + (4 * 1)
Answer: 9564 = (9 * 1000) + (5 * 100) + (6 * 10) + (4 * 1)
5th grade math function - Example problem: 3
Find the sum of the two algebraic functions (x + 52x ^5 - 15) and (11x - 52)
Solution:
The given two functions are (x + 52x ^5 - 15) and (11x - 52)
Add the given two functions, we get
= (x + 52x ^5 - 15) + (11x - 52)
Expand the above functions, we get
= (x + 52x ^5 - 15 + 11x - 52)
= 52x3 + 12x - 67
Answer: (x + 52x ^5 - 15) + (11x - 52) = 52x ^5 + 12x - 67
5th grade math functions - Practice problems:
1. Find the expand form for the given number 75689.
[Answer: 75689 = (7 * 10000) + (5 * 1000) + (6 * 100) + (8 * 10) + (9 * 1)]
2. Find the simple interest on sum of 6000 for 4 years at the rate of 10%.
[Answer: The simple interest value is 2400]
3. Add the given two algebraic functions f(x) = 89x + 15 and g(x) = 8x2 - 26
[Answer: 8x2 + 89x – 11]
