How do you subtract #83- 52#?

1 Answer

#color(white)(-)83#
#ul(-color(white)(0)52)#
#color(white)(000)31#

Explanation:

#color(white)(-)83#
#ul(-color(white)(0)52)#

To subtract, we start from right and move left. The first thing we do is take 3 and subtract 2:

#color(white)(-)83#
#ul(-color(white)(0)52)#
#color(white)(0000)1#

And then we move to the next column and take 8 and subtract 5:

#color(white)(-)83#
#ul(-color(white)(0)52)#
#color(white)(000)31#
