All 4 cards in this deck

What does $ab$ mean in algebra?

$a \times b$ — the multiplication sign is left out.

What does $a^2b$ mean written out as a product?

e.g. expand the notation

$a \times a \times b$ — only the $a$ is squared.

True or false? $3y$ means $3 + y$.

False. $3y$ means $3 \times y$.

True or false? In algebraic notation the number is written before the letter, so you write $5t$ and not $t5$.

True. The coefficient goes first, e.g. $5t$.
