Written from the section, each card quoting the span it came from. The ones you miss come back sooner.
What this needs
Learn these first — this section will not make sense without them.
Nothing in the algebra book is a prerequisite for this section.
What this touches
Algebra that turns up here. Not a blocker, but this is where you will see it used.
Every measured quantity in this section is written in scientific notation (298,000 kg as 2.98×10⁵ kg, 0.0000025 kg as 2.5×10⁻⁶ kg) and every SI prefix is defined as a power of ten (kilo = 10³, micro = 10⁻⁶) — misreading the sign of the exponent when converting a decimal into a prefix is the standing error this section relies on the student having already outgrown.
