History of Mathematics High School - Essay Example The rods are placed in columns with the rightmost column representing the units, the next column representing the tens, then the nest representing the hundreds, and so on. Red rods represent the positive numbers while black rods represent the negative numbers. For example, the number 25 will have a representation using the rods where 5 will be placed in the rightmost column and 2 will be placed in the next column. An empty column represents zero (Chinese Rod Numerals (Counting Rods)). The rods were carried in a pouch and placed on a counting board which had compartments corresponding to the ones, tens, hundreds place and so on. Each compartment was split into two parts. The right part is for the heng (1 to 9) rods and the left part was for the tsangs (10 to 90) rods. Whole numbers are represented by combining these two types of rods. After the rods were placed in their rightful compartments, they were then manipulated by repositioning and reforming them as required by the arithmetic operation. The first evidence of the existence of zero is from the Sumerian culture in Mesopotomia some 5,000 years ago (Wallin). This was in the form of cuneiform symbol for numbers where a slanted double wedge between two cuneiform symbols indicates an absence of a number or zero.

This claim can be supported by Sharry’s edition of the Life Safety Code Handbook (1978), which states that the occupancy load of mercantile or retail stores is not less than 1 person for each 30 square feet gross floor area of sales space; for office or business occupancy, it is no less than 1 person per 100 square feet of gross floor area; and finally, for apartments or residential occupancy, it is 1 person per 200 square feet gross floor area. From these figures alone, we can already foresee and surmise that the first floor will be the most densely populated followed by the second and third floors, and then the fourth and fifth. Perhaps as the resident site-safety engineer, though there is limited information given in this situation, it is imperative to assess live loads as close as possible to reality. This would give a crude idea of the dispersal of people in any given building and the maximization of other safety measure that can mitigate any damage, distortion, or discomfort to its
