Parentheses are the symbols that curve forwards and backwards. When numbers and operations are inside the parentheses, it forms a group and it tells you what to do first in a math problem.

Brackets work exactly the same way as parentheses do. Brackets have a shape that looks more boxy but they mean exactly the same thing. Usually, you will see parentheses more frequently than brackets, but brackets are used a lot too.

If they appear in one equation at the same time, you work on the numbers inside the parenthesis first then work on the numbers inside a bracket

Answer:

The certificate will be worth $5,559.92 on Ruth's 19th birthday.

Step-by-step explanation:

The compound interest formula is given by:

$A = P(1 + \frac{r}{n})^{nt}$

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

In this problem, we have that:

$P = 1000, n = 1, r = 0.1, t = 18$
