Solve equations with whole numbers

What you'll learn

• Identify the greatest possible error (GPE) in measurements given to a specified degree of precision, expressing the GPE as plus or minus half of the smallest unit of measure, with 100% accuracy in at least 4 out of 5 examples.
• Calculate the upper and lower bounds of a measurement by adding and subtracting the greatest possible error (GPE), respectively, and expressing the result as an interval, solving at least 3 out of 4 problems correctly.
• Explain how the precision of a measuring instrument affects the greatest possible error (GPE) and, consequently, the range of possible true values, in a written response of at least 3 sentences, demonstrating understanding of the inverse relationship.
• Apply the concept of greatest possible error (GPE) to solve real-world problems involving measurement, such as determining the acceptable range of dimensions for manufacturing parts, achieving correct solutions in at least 2 out of 3 applied problems.
