Everyone knows how to add numbers by hand, right?––Well, I hope so, but for anyone who needs a quick reminder:
1342, you proceed as follows:
place the larger (value wise, not number of digits) number above the smaller number and match up the digits
draw the plus sign (+) to the left of the equation on the second row. The plus sign must be flush with the left side.
17282 + 1342
draw a line of dashes (-) with one dash in each column of the digits of the first line
17282 + 1342 -----
evaluate the expression and write the digits above each column if you need to 'carry' them
1 17282 + 1342 ----- 18624
Your output is what you get after applying step #4. You may have trailing whitespace, but there may not be any leading zeroes.
You must write a program or a function that prints or returns the output.
The input can be taken as either two separate inputs or an array with two items; the type of the inputs can be either string or integer.
This is code golf so shortest code in bytes wins!
The largest number you could expect to receive as output/the sum is the largest integer that your system will display without exponents (thanks to Adám).
Input: 1596, 8404 Output: 1111 8404 +1596 ---- 10000 Input: 1776, 76 Output: 11 1776 + 76 ---- 1852 Input: 123, 456 Output: 456 +123 --- 579
