# Working with time

What is Noon and Midnight?

A.M. and P.M. start immediately after Midnight and Noon (Midday) respectively.

This means that 00:00 A.M. or 00:00 P.M. (or 12:00 A.M. and 12:00 P.M.) have no meaning.

Every day starts precisely at midnight and A.M. starts immediately after that point in time e.g. 00:00:01 A.M. (see also leap seconds)

To avoid confusion timetables, when scheduling around midnight, prefer to use either 23:59 or 00:01 to avoid confusion as to which day is being referred to.

It is after Noon that P.M. starts e.g. 00:00:01 PM (12:00:01)

A.M. abbreviation ante meridiem

P.M. abbreviation post meridiem

# Solar Energy

What is solar energy and how could we use it as a resource to power the things we use every day?

Solar energy is the energy of sunlight collected and used to provide electricity, to heat water, and to heat or cool homes, businesses or industry.

Sunlight is a clean, **renewable** source of energy. It is a sustainable resource, meaning it doesn’t run out, but can be maintained because the sun shines almost every day. Coal or gas are not sustainable or renewable: once they are gone, there is none left. More and more people are wanting to use clean, renewable energy such as solar, wind, geothermal steam and others. It is called **‘Green Power’**.

# Rounding numbers

Rounding Numbers

A rounded number has about the same value as the number you start with, but it is less exact.

For example, 341 rounded to the nearest hundred is 300. That is because 341 is closer in value to 300 than to 400. When rounding off to the nearest dollar, $1.89 becomes $2.00, because $1.89 is closer to $2.00 than to $1.00

Rules for Rounding

Here’s the general rule for rounding:

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 401

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30

What Are You Rounding to?

When rounding a number, you first need to ask: what are you rounding it to? Numbers can be rounded to the nearest ten, the nearest hundred, the nearest thousand, and so on.

Consider the number 4,827.

4,827 rounded to the nearest ten is 4,830

4,827 rounded to the nearest hundred is 4,800

4,827 rounded to the nearest thousand is 5,000

All the numbers to the right of the place you are rounding to become zeros. Here are some more examples:

34 rounded to the nearest ten is 30

6,809 rounded to the nearest hundred is 6,800

1,951 rounded to the nearest thousand is 2,000

In your maths books round these numbers to the nearest 100

99, 234, 674, 889, 455, 239, 588, 341, 774, 178, 499, 451, 673

Round these numbers to the nearest 1,000

5,999, 3,501, 8,456, 3,555, 9,999, 3,499, 7,245, 4,522, 8,999, 3,567

Round these numbers to the nearest 10,000

56,999, 43,455, 72,899, 23,645, 34,001, 56,767, 98,999, 21,534
