\[ b = 1 - \frac{3}{2} = -\frac{1}{2} \]

["Understanding the Expression: ( b = 1 - \frac{3}{2} = -\frac{1}{2} )", "In basic algebra, solving for ( b ) often involves simple subtraction of fractions. One clear and instructive example is the equation:", "[\nb = 1 - \frac{3}{2} = -\frac{1}{2}\n]", "### What Does This Equation Mean?", "This expression evaluates the difference between the number 1 and the fraction (\frac{3}{2}). Since (\frac{3}{2}) is greater than 1, subtracting it from 1 results in a negative value.", "### Step-by-Step Breakdown", "1. Express Both Terms with a Common Denominator:\n To subtract (\frac{3}{2}) from 1, rewrite 1 as a fraction with denominator 2:\n [\n 1 = \frac{2}{2}\n ]\n Now the expression becomes:\n [\n b = \frac{2}{2} - \frac{3}{2}\n ]", "2. Subtract the Fractions:\n Since the denominators are the same, subtract the numerators:\n [\n b = \frac{2 - 3}{2} = \frac{-1}{2}\n ]", "3. Final Simplified Form:\n [\n b = -\frac{1}{2}\n ]", "### Key Takeaways", "- This calculation illustrates a basic operation in fractions: subtracting a larger unit fraction from a whole number.\n- Recognizing that ( \frac{3}{2} = 1\frac{1}{2} ), it follows that taking 1 from ( \frac{3}{2} ) leaves a negative difference.\n- Understanding this helps build foundational skills in solving linear equations and working with rational numbers.", "### Why This Matters", "Knowing how to compute and simplify expressions like ( b = 1 - \frac{3}{2} ) is essential in math education, helping students master arithmetic, fractions, and algebraic reasoning.
