How are the mnemonic devices LA US and LP UN used in operating signed numbers?

These mnemonic devices were developed by SHERWIN E. BALBUENA, mathematics teacher of Cabitan NHS, Mandaon, Masbate, Philippines", to teach his students with disabilities the rules in operating signed numbers. LA US means "Like signs Add, Unlike signs Subtract". This device lets the student remember the rule in adding signed numbers. LP UN means "Like signs Positive, Unlike signs Negative". This device lets the student recall the rules in finding the product and quotient of two signed numbers.

Can the same rules be used to determine the sign of an integer sum and an integer product?

No.For the sum of integers:-- two positives make a positive-- two negatives make a negative-- the sum of mixed signs is the sign of the one with the greater absolute valueFor the product of integers:-- like signs make a positive-- unlike signs make a negative

What will be the difference when subtracting two integers with different signs?

Subtracting: Positive - Negative = Positive Negative - Positive = Negative No that is not the way it goes. It is positive+negetive=either counting on which integer is bigger negative+negative=positive positive+positive=positive positive x negetive=negative negative x postitve= negative negative/positive=negative positive/negative=negetive thanks The top is right though because subtracting a negative is like adding so you could never get a negative and subtracting from a positive from negative will always be a negative. The question was for integers with different signs so you don't need to do "positive + positive"

What is the quotient of two real numbers with the same sign is?

++ = + +- = - Like signs always give me plus. Unlike signs always give me minus when I multiply! My maths teacher made us learn that! :D
