Lesson Fifty-five: Missing Numbers

Here are all the multiples of ten up to 100: 


	10 x 1 = 10			10 x 6 = 60

	10 x 2 = 20			10 x 7 = 70

	10 x 3 = 30			10 x 8 = 80

	10 x 4 = 40			10 x 9 = 90

	10 x 5 = 50			10 x 10 = 100
Armed with these facts you should be able to easily answer any of these missing number problems: 

	10 x __ = 10			10 x __ = 60

	10 x __ = 20			10 x __ = 70

	10 x __ = 30			10 x __ = 80

	10 x __ = 40			10 x __ = 90
