Question 339953
four and four fifths + two and one third - three and eight fifteenths
<pre><b>
{{{4&4/5}}}{{{""+""}}}{{{2&1/3}}}{{{""-""}}}{{{3&8/15}}}

Add the first two numbers first:

{{{matrix(4,8,

"",   4&4/5,""="",4&12/15,    "" ,     ""  ,   "" ,   "", 
""+"",2&1/3,""="",2&5/15,     "" ,     ""  ,   "" ,   "", 
"" ,  "___",   "","___",     "" ,     ""  ,   "" ,   "", 
"",     "",    "", 6&17/15, ""="", 6+1&2/15, ""="", 7&2/15)}}}

Now we subtract the third number from that answer:

{{{matrix(4,6,

"",   7&2/15,""="",6&17/15,    "" ,     ""  ,   
""-"",3&8/15,""="",3&8/15,     "" ,     ""  ,    
"" ,  "___",   "","___",     "" ,     ""  ,   
"",     "",    "", 3&9/15, ""="", 3&3/5)}}}
