💡Distance is nonnegative.

💡Distance cannot be negative.

💡Two equal-distance points.

💡Only zero is zero units from zero.

💡Absolute value is nonnegative.

💡Remove outside constants and coefficients.

💡Write both branches.

💡Both branches coincide.

💡Its graph is V-shaped.

💡Negative inputs are negated.

💡The visible horizontal sign is reversed.

💡It reflects across the x-axis when negative.

💡Larger magnitude is steeper.

💡Use x minus h.

💡Its displayed sign is direct.

💡Use E = -a, not -E = -a unless equivalent.

💡Order does not affect absolute difference.

💡Use the original equation.

💡Their average is h.

💡Inspect after isolation.
