Baiyun, once again you have provided an excellent answer using
the model drawing
method to solve the question to which the PSLE students are
taught to understand.
Your presentation is also very beautiful too.
Indeed, I strongly recommend Baiyun to be the moderator of
Homework Forum for
the Primary school Mathematics Questions as he or she provides
the answers
using model drawing method, not using secondary school algebra
to which many
forumers use to solve primary school mathematics
questions. Primary school
mathematics students are only taught the model drawing and the
guess and check
method to solve the questions.
Baiyun, well done ! Keep up the good work.
