#### Converting Kilometres to Miles

The formula to convert kilometres to miles is number of (kilometres / 8 ) X 5
Convert 80 kilometres into miles
80/8 = 10
multiplied by 5 is 50 miles

### Temperature Conversions

Shortcut to convert Fahrenheit to Celsius and after that vice versa.
The answer you will get will not be an exact one, but it will give you an idea of the temperature.
Convert Fahrenheit to Celsius:
Take 30 away from the Fahrenheit, and then divide the answer by two. This is your answer in Celsius.
For Example:
74 Fahrenheit – 30 = 44. Then divide by 2, = 22 Celsius.
So 74 Fahrenheit = 22 Celsius.
Convert Celsius to Fahrenheit
Convert Celsius to Fahrenheit just reverse:
Double it and then add 30
30 Celsius double it, is 60, then add 30 is 90
30 Celsius = 90 Fahrenheit
NOTE : The answer is not exact but it gives a rough idea about the answer (Option).

. Mental Math Skills:

• Use Estimation: Estimation helps you quickly assess whether an answer is reasonable. Round numbers and use approximations to simplify calculations.
• Break Down Complex Problems: Divide complex problems into smaller, more manageable steps to solve them step by step.

2. Multiplication and Division:

• Learn Multiplication Tables: Memorize multiplication tables up to 12 to perform multiplication quickly.
• Divisibility Rules: Familiarize yourself with divisibility rules for numbers like 2, 3, 4, 5, 6, 9, and 10 to quickly identify factors and multiples.
• Long Division Shortcut: When dividing by a two-digit number, estimate the quotient, multiply the divisor by the estimate, and adjust as needed.

• Left-to-Right Addition: Add numbers from left to right rather than right to left for quicker mental calculations.
• Number Line Addition: Use a number line to add or subtract numbers, especially when dealing with negative numbers.

4. Fractions, Decimals, and Percentages:

• Convert Fractions to Decimals: To convert fractions to decimals, divide the numerator by the denominator.
• Percentage Tricks: Learn common percentage shortcuts, such as finding 10% (by moving the decimal point), 1% (by dividing by 100), and 50% (by halving).
• Simplify Fractions: Reduce fractions to their simplest form to make calculations easier.

5. Algebra:

• FOIL Method: Use the FOIL method (First, Outer, Inner, Last) to multiply two binomials quickly.
• Factorization: Practice factorization techniques to simplify algebraic expressions.

6. Geometry and Trigonometry:

• Pythagorean Theorem: Memorize the Pythagorean Theorem (a^2 + b^2 = c^2) for right triangles.
• Trigonometric Ratios: Learn the sine, cosine, and tangent ratios for trigonometry problems.

7. Word Problems:

• Identify Keywords: Look for keywords like “sum,” “difference,” “product,” or “percent” in word problems to help you set up equations.
• Draw Diagrams: For geometry and spatial problems, draw diagrams to visualize the situation.
