alone. Nor was it used at the end of a number. Thus numbers like 2 and 120 (2×60)‚ 3 and 180 (3×60)‚ 4 and 240 (4×60)‚ looked the same because the larger numbers lacked a final sexagesimal placeholder. Only context could differentiate them. India The concept of zero as a number and not merely a symbol for separation is attributed to India‚ where‚ by the 9th century AD‚ practical calculations were carried out using zero‚ which was treated like any other number‚ even in case of division.[9][10] The

fractions are ½ and ¾. These are proper or regular fractions. Some fractions are called mixed numbers. These are represented by a whole number with a fraction (proper fraction). 1 ½ and 2 ¾ are good examples. An improper fraction has a larger number on the top than on the bottom‚ such as 9/8. I will explain how to convert these fractions to decimals. I will show you how to change an improper fraction to a mixed number. Operations (addition‚ subtraction‚ multiplication‚ and division) will be explained as

Discuss the approach to teaching math taken in the Montessori classroom. Montessori is an approach which many have adopted these days as a teaching method for children in preschool. The materials which they use create an environment that is developmentally appropriate for the children. Montessori believes that with the helped of trained teachers and the proper environment which the children are placed in‚ intelligence and different skills will be developed in the child (Casa Montessori‚

credible. What the problem of the week is asking is that the number that you put in the boxes 0-4 is the number of numbers in the whole 5-digit number. For example‚ if you put zero in the “one” box‚ you would be indicating that there is zero ones in the number. Another example is if you put a two in the “three” box. This would indicate that there are two threes in the whole 5-digit number. I was asked to find solutions where are the numbers would work in heir perspective boxes. From there I started

first exercise introduced to the child to prepare him for these operations; is the “Number Rods”. The ten number rods are graduated in length from 4 inches length for the shortest one‚ to 40 inches length for the longest one. The different four inch sections are alternately colored red and blue and can be counted on each rod. So ‚ each rod consists of distinct countable units‚ united together to represent a number. This overcomes the difficulty of adding one unit after another in a sum total. “The

Practicing number name rhymes is another way of reinforcing them in the childs mind‚ and they are usually associated with finger play‚ so not only are they more enjoyable for young children‚ but it means the number is also linked to the name. Games and stories that we enjoy with younger children is will also involve the number names‚ and reinforce them. Counting by Rote Counting by rote basically means counting without

decimal integral numbers to binary (don’t we?) by the simple method of dividing succesively by 2 and using the remainders but what happens when we are trying to convert a decimal number which has a fractional part? First we can see that it is obvious that the integral part of a decimal number will always be represented by an integral binary (with no fractional part) while the fractional part of a decimal number will always be represented by a fractional part of a binary number (with no integral
