1121. Mirage operations

    Dear Teacher:
    I've called mirage operation to any mathematical operation whose result doesn't change when the digits of its operands are reversed. So,  31 · 26  and  48 + 95  are mirage operations because

31 · 26  =  62 · 13    (=  806) 

48 + 95  =  59 + 84    (=  143)

    Who can find mirage multiplications and mirage additions?

    I wanted my pupils to solve this challenge of Pepe Chapuzas's... It was his classmate Nina Guindilla, again, who did it... She matched operands with lines...
