How can adding doubles multiply by 2?
Multiplication (of positive integers) can be defined as repeated addition. Thus, 2 x 23, for example, is the same as 23 + 23, while 3 x 20 = 20 + 20 + 20. Thus, adding a number to itself is equivalent to multiplying it by 2.Multiplication (of positive integers) can be defined as repeated addition.

What size is a 20 x 30 cm pan?
20 x 30 = 600 square cm
What is 20 over 30 simplified?
20/30 = (2 x 10)/(3 x 10) = 2/3
Find the surface area of a triangular prism with height 30 in and a right triangle base with side lengths 15 in and 20 in and hypotenuse length 25 in?
Surface area = 2 x area_triangular_ends + areas_of_3_rectangular_faces Surface area = 2 x (15 x 20)/2 + 30 x 15 + 30 x 20 + 30 x 25 = 15 x 20 + 30 x (15 + 20 + 25) = 300 + 30 x 60 = 2100 in2
What is 30 times 20?
When multiplying with zeros you just remove the zeros and multiply the other digits then add the amount of zeros you removed to the answer. 30 x 20 = 3x2 =6 then add two decimal to the right with zeros. 600 30 x 20 = 600
