For a moment, take a break from the stress of work life.
Without the use of simultaneous equations, see if you can find a way to determine the numerical value of "Sun" and "Moon" below :
Sun + Moon = 25
Sun - Moon = 5
P.S. This is a real mathematical question given to a primary one student at school! :o

Hi GB
15 and 10.. but have to confess that I sort of used mental simultaneous equation..
After trying out various methods, I think the best way is by drawing model. Easiest to explain to child.
Hey try this other one:
Fries + Coke = 21
Coke - Fries = 5
What is the value of Fries and Coke?
