Explanation:
To add two large integers like this, it is probably easiest to write one above the other and add column by column from the right...
#color(white)(0+)562685886#
#underline(color(white)(0)color(black)(+)894863328)#
#color(white)(+)1457549214color(white)(00) larr "result"#
#color(white)(+0)11color(white)(0)11color(white)(0)111color(white)(000) larr "carried digits"#
So:
#6+8+0 = 14" "# i.e.#4# and carry#1#
#8+2+1 = 11" "# i.e.#1# and carry#1#
#8+3+1 = 12" "# i.e.#2# and carry#1#
#5+3+1 = color(white)(0)9" "# i.e.#9# and carry#0#
#8+6+0 = 14" "# i.e.#4# and carry#1#
etc.
