Find the value of n using equations 4 x 27 + 5 x 34 - 94 = n

108 + 5 x 34 - 94 = n 108 + 170 - 94 = n 278 - 94 = n 184 = n

Write an equation 2 times as many as 8 is 16

2 x 8 = 16

Find the product of 4 x 19=___ using the distributive property

4 x 10 = 40 and 4 x 9 = 36 40 + 36= 76 4 x 19 = 76

Record the product 4 x 19 =___ using expanded form

4 x 19 = 4 x (10 + 9) = (4 x 10) + (4 x 9) = 40 + 36 = 76
