Using Order of Operations to Create Numerical Expressions

Explore the effects of the order of operations on the value of an expression. Strategically arrange the digits of an expression to create the largest possible number.
Putting It All Together
[i]Answer these open ended questions on your own or with others to form deeper math connections.[/i]
Which operation has the greatest effect on the result of the expression?
Where would you put the largest number? Why?
Which number would you leave out of the expression? Why?
