Welcome to a video that will show how to square a two digit number that ends in five quickly and without the use of a calculator. The result of squaring any two-digit number that ends with five starts with the number you get by multiplying the first digit of the number you are squaring with […] ## Square Any Two-Digit Number without Using Calculator

Welcome to a video that will show how to square any 2 digit number without the use of a calculator. The first step is to determine the distance from the number you are squaring to the nearest multiple of 10, and then step 2 add the distance to one factor and subtract the distance from […] ## Approximating Square Roots Using Division (No Calculator Required)

Welcome to a lesson on approximating square roots. Using division this process will allow you to approximate a square root without the use of a calculator. Let’s begin by approximating the square root of 23. Since we know the square root of 16 equals 4 since 4 squared equals 16, and the square root of […] ## Ex: Evaluate Logarithmic Expressions without a Calculator – Common Log

We want to evaluate the given log expressions. Notice how for each log the base is not given, so we know these are common logs, meaning each log is base 10. To help us evaluate these log expressions, we’ll form a log equation by setting the expression equal to x, then we’ll write the log […] ## Fix For My HP Computer Screen That is Black, No Display, Distorted, Has Lines Or Glows
