Often it is a good idea to start simple, before getting more complicated.
First let us review some basic mathematical operations which may already be familiar.
Mathematically, an operation is some action performed onto some numbers (called
the operands) to yield some new value. For example in a + b, + is the operation,
with a and b being the operands.
We will begin with the simple operation of addition, in which we take two numbers called the addends or summands and merge them to yield them sum.
Addition has a few important properties to note:
- It is commutative, meaning that the order of the operands does not affect the result. That is,
a + b = b + a. - It is associative, meaning that the order of addition operations among multiple operands will not affect the result. That is,
(a + b) + c = a + (b + c).
Problem Statement
Input Data
In the box below titled "Test data" you will find a list of values on multiple lines.
The first will be an integer, indicating how many addends will be listed.
That number of integers will then follow, each on its own line.
Feel free to copy and paste the data from the textbox to wherever you wish.
Answer
In the box titled "Your answer", please paste the total sum of all the addends.
Be sure not to include a decimal point nor any leading/trailing zeros in the final answer.
Solution
In the box titled "Your solution", please paste whatever program or code you used to obtain your answer.
Whatever you put into this box doesn't get checked by the server, but you will be able to reference again later.
Example
input data:
3
12
345
6789
answer:
7146
In the above example, the first line of the input data indicates there will be 3 integers to add together,
which appear on the following lines.
12 + 345 + 6789 = 7146
