Now you try! 13 x 28 = First, multiply 10 x 20= 200Then, multiply 10 x 8 = 80Next, multiply 3 x 20 = 60Finally, multiply 3 x 8 = 24Add the products to get 364!
32 x 54First, multiply 30 x 50= 1500Then, multiply 30 x 4 = 120Next, multiply 2 x 50 = 100Finally, multiply 2 x 4 = 8Add the products to get 1,728!
