computation. It is especially important in positional notations. Positional notations‚ is a numerical system in which each position is related to the next by a constant multiplier (ex. 10). Positional notations require an indication of the number zero because zero is a placeholder. It allows us to tell the different between 23‚ 203‚ and 230. Without zero‚ it would be impossible to tell them apart. The decimal system‚ for example‚ uses 10 as a base‚ and zero is required for 10 to be the base. Otherwise‚ it would

1.PERCENT ● DEFINITION OF PERCENT - Percent means parts per 100 The symbol is % Example: 25% means 25 per 100 ● CONVERSION TECHNIQUES - ✔Changing percent to decimal Change a percent to a decimal. Move the decimal point two places to the left. In a percent‚ the decimal point would come at the end of the last number (for 75%‚ envision that it looks like 75.) Examples: 75% converts to .75 40% converts to .40 3.1% converts to .031 ✔Changing decimal or whole number to percent Change a decimal

of void‚ the Eastern civilisations are credited with the invention of zero. The Western civilisations‚ on the other hand‚ struggled for almost two millennia to finally accept zero. The history of zero from merely a placeholder in place value systems (digit) to finally becoming accepted as a number has a very long history in Western civilisations. This was mainly due to their strong rejection of the concept of void. The Eastern civilisations‚ fortunately‚ were never so fearful of the idea of

Rounding Mixed Decimals to the Nearest Tenth A concept in mathematics that students need to learn in elementary school is to round mixed decimals to the nearest tenth. This essay describes how I would teach this concept to a group of fourth grade students. To begin‚ I would identify the prerequisite skills that students need in order to master this concept. First the students need to understand place value of whole numbers and decimals; this is necessary because rounding can affect the amount
