What is an array

An arrangement of objects, pictures, or numbers in columns and rows is called an array. Arrays are useful representations of multiplication concepts.

200

Describe the rule of multiplying by 10's

example:

14 x 100= 1400

14 x 10= 140

14 x 1000= 14000

take the number 14 or the base number and attach the number of zeros from the second number. 

300

Solve

12 x 100

1200

400

5 x 60= 300

Why are there two zeros in the answer? 

I know that when I multiply a whole number by ten, I add a zero to the end. Since 5x6 = 30, 5x60 = 300.

500

Add parenthesis to make the statement true

5 x 3+8 -1 = 54

5 x (3+8) -1 = 54
