to split all expressions into terms.
A term starts with a + or - that is NOT in parentheses.
Thus, to evaluate 5*4 +3(6-8)+3^2-8+5
the student writes 5*4 +3(6-8) +3^2 -8 +5
Each term is evaluated +20 -6 +9 -8 +5
The reults are now combined according to the rules of Algebra. +34 -14 =
+10
Students discover that the individual terms can be evaluated in ANY order.
Creating terms is particularly important with expressions such as 10-3(2)
where students tend to write 7(2)=14
Of course, all this assumes that students know how to oparte with signed
numbers.
