Scientific notation is a common way of writing very large numbers. In everyday life we see this when dealing with cell phone storage. If a phone has 10 gigabytes of hard drive space that means that it has 10×109 bytes of space. A megabyte is 1×106 bytes. If our phone with 10 gigabytes of free storage downloads a game that takes of 76 megabytes, how much free storage is left?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
