Stress Management Tips
Physical activity plays a key role in reducing and preventing the effects of stress. Make time for at least 30 minutes of exercise, three times per week. Nothing beats aerobic exercise for releasing pent up stress and tension.
Use hundred when there is a specific number, and use hundreds when you don't know or can't count how many. This rule also applies to thousand/thousands and million/millions. This skeleton is thousands of years old. This skeleton is three thousand years old.
When saying numbers, always use the singular form:

Two hundreds and fifty
7,812 = Seven thousand, eight hundred and twelve
Seven thousands, eight hundreds and twelve
$10,000,000 = Ten million dollars
Ten millions of dollars
