31.2 X 10 = 3.12 X 10 Notice the larger number has the smaller exponent
31.2 X 10 = 3.12 X 10 Using the same concept what exponent would go beside the 10? 312 x 10 Notice the larger number has the smaller exponent
(5.45 X 10 ) + (3.12 X 10 )
(5.45 X 10 ) + (3.12 X 10 ) 31.2 X 10
(5.45 X 10 ) + (3.12 X 10 ) 31.2 X 10
(5.45 X 10 ) + (3.12 X 10 ) 31.2 X 10
(5.45 X 10 ) + (3.12 X 10 ) 31.2 X 10
(2.67 X 10 ) - (4.2 X 10 )
(2.67 X 10 ) - (4.2 X 10 )
(2.67 X 10 ) - (4.2 X 10 )
(2.67 X 10 ) - (4.2 X 10 )
