What is the peculiarity of the numbers in the white boxes?

Now complete the blank boxes.

Find and write the patterns from the boxes.

Let's look at the design and calculate how many stamps I had. Each page has $18$ stamps.

Number of stamps in the first $7$ pages $\Rightarrow$ _____ $+$ _____ $=$ _____

Write down the multiplication table of $7$.

The multiplication $5\times 3=15$ has been shown in the table before.

Fill in the right numbers in the empty boxes.

Let's look at the design and calculate how many stamps I had. Each page has $18$ stamps.

Number of stamps in the first $9$ pages $\Rightarrow$ _____ $+$ _____ $=$ _____

Each packet have $19$ lozenges.

Four packets have $=$ _____$\times$ _____ $=$ (_____ $+$ _____$+$ _____$+$ _____) $=$ _____ lozenges.

Identify the number that is different from the rest and draw circle around it.
