$6.75 + h
Maya wrote the expression 3+5+4.5 to represent the total distance that she traveled. Which statement best describes Maya's expression? Maya's expression will generate the correct sum because of the associative property.
you can use any letter as long as you know what it means and represents.
X+6. Variable (x)
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
