Let one number by x and the other number be y.  Sum means add.  Difference means subtract.  So they are telling you that x + y = 56.  And your second equation is x - y = 10.  You have two equations and two unknowns.  Do you how to solve this?  I can explain if not.

You don't have to guess.  It's easy to solve.  In the first equation, isolate x  so that x = 56 - y.  Then substitute that in for x in the second equation.
