Use the order of operations to solve the following and explain using a T-chart – 2(7 – 25 ÷ 5)3 Evaluate the following expression Let x = 3 y = (-2) z= (-1) 2) 3x2 + 2y – 5z + xyz

2 Combining like terms with subtraction with no exponents
Example 1) x – 2x 2) 2x + 4x – 3x – 5x 2x + 5x + (-3x) + (-5x) 3) 3xy – 4xy + xy – 7xy 3xy + (-4xy) + xy + (-7xy) 4) 7p + 3p – 4p – 5p 7p + 3p + (-4p) + (-5p)

3 More Combining with exponents
1) x2 + 3x2 – 7x2 x2 + 3x2 + (-7x2) 2) -5x3 – 2x3 + 3x3 – 4x3 -5x3 + (-2x3) + 3x3 + (-4x3) 3) 3x3 – 4x4 – 5x3 – 2x4 + 8x5 3x3 + (-4x4) + (-5x3) + (-2x4) + 8x5
