Pronunciation: [sˈa͡ɪn tˈa͡ɪmz] (IPA) 
The spelling of "sign times" can be tricky due to the silent letter "g" in the word "sign". The IPA phonetic transcription for this word is /saɪn taɪmz/. The "s" sound in "sign" is followed by the "aɪ" diphthong, which represents the vowel sounds in "eye". The "n" and "t" sounds are straightforward, before moving onto the plural "z" sound at the end of "times". Overall, "sign times" is pronounced as "sine times".
"Sign times" is a mathematical term that refers to the operation of multiplying two real numbers that have different signs, one being positive and the other negative. It specifically applies to the product of a positive number and a negative number.
When performing sign times, the resulting product is always negative. This means that regardless of the values of the two numbers being multiplied, their signs determine the sign of the final result. For example, if a positive number is multiplied by a negative number, the outcome will always be negative.
This operation can be understood by considering the concept of opposites and how they interact. When opposite numbers are multiplied, they nullify each other's value, resulting in a negative product. For instance, multiplying 4 by -3 results in -12, and multiplying -6 by 5 gives -30.
Sign times is a fundamental operation used in algebra and applied in various mathematical contexts, such as solving equations, simplifying expressions, or calculating the area of shapes with negative dimensions. Understanding the rules of sign times is crucial for performing accurate calculations and ensuring the correct interpretation of mathematical operations involving positive and negative numbers.
