subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations. To add integers having the same sign‚ keep the same sign and add the absolute value of each number. To add integers with different signs‚ keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite

A - Find the LCM of two Numbers LCM and HCF of two integers LCM of two numbers Example 1: Find the LCM of 66 and 28 . Find the prime factorization of the two numbers. 2 66 3 33 11 11 1 2 28 2 14 7 7 1 28 = 22 x 7 66 = 2 x 3 x 11 Any multiple of 66 will also have 2‚ 3 and 11 as its factors. Likewise any multiple of 28 well have 2 and 7 as its factors. The common multiple will have all the prime factors of the two numbers as its factors. Where a prime factor is found in both the two numbers‚ the

Integer Programming 9 The linear-programming models that have been discussed thus far all have been continuous‚ in the sense that decision variables are allowed to be fractional. Often this is a realistic assumption. For instance‚ we might 3 easily produce 102 4 gallons of a divisible good such as wine. It also might be reasonable to accept a solution 1 giving an hourly production of automobiles at 58 2 if the model were based upon average hourly production‚ and the production had the interpretation

Explain the main differences among integers‚ rational numbers‚ real numbers‚ and irrational numbers. Integers are the natural numbers of (0‚ 1‚2‚3‚4….)and the negative non zero numbers of (-1‚-2‚-3‚-4….)and so forth. Integers are numbers without a fractional or decimal component. Example: 23‚ 5‚ and -567 are integers‚ 8.45‚ 5½‚ and √2 are not integers. Integers are any number that can be expressed as the ratio of two integers. All integers are rational because integers can be expressed as a ratio of
