Chapter 1 · Language of Mathematics
✳️
Verify
Substitute and confirm — don't solve from scratch

🔒
Using the Given Information
Turn "given that…" into an equation; inputs vs outputs
Locked
🔒
Prove
One side only, general algebra, no proof by example
Locked
🔒
Show That
Verify, find, or prove — and never work backwards
Locked
🔒
Hence
Use part (a), spot the disguise, reject impossible values
Locked
