Description: This mechanical tin toy calculator is a lot of fun to learn math multiplication tables on. Mr. Smart never loses patience at having to answer questions. To multiply numbers, set the monkey’s feet to point to two numbers. Its fingers locate their product. To square a number, set the left foot to point to the number and set the right foot to point to the symbol of a square at the far right. The fingers then locate the square of the number. To divide, set one foot to point to the divisor and arrange the fingers to point to the dividend. The other foot then points to the quotient. To factor, make the fingers point at a product, the feet then point to the factors. Mr. Smart is a delightful educational tin toy. He measures 5 ½” X 6 1/2” and comes in a nice gift box. He has sharp edges so please exercise caution with young children.
