**Hello World!**

It is easy to write "Hello World!" in Bloky. Let's take a look.

**Arithmetic**

This is the first code how to compute a calculation in maths & science.

Example: Calculation of 2 + 3 is as follows.

Exercise : Write codes of the following simple calculations.

a. (2 + 3) x 2

b. 3^{2} – 1

c. Other calculation

**Variable**

Variable is a basic thing both in maths & science.

Example:

a = 3

b = 2

c = a x b

The above example can be written as follows.

Exercise : Create a code to determine the area and circumference of a circle with any radius r, use pi = 3.14.

**Logic**

Logic is used to specify a condition in coding.

Example: This code will determine any number x whether it is odd or even.

Exercise : Create any code which contains logic if, else if, and else.

**Loops**

Loops are used to repeat a piece of code.

Example: Writing a sequence from a to b by c, where a, b, and c are any numbers, is as follows.

Exercise : Create a code to find the sum of the sequence above.

**Maths & Science Projects**

Make your creative codes in Bloky of the cases below.

1. To convert any temperature T in Kelvin to Celcius.

2. To assess a solution whether it is acidic, or basic, or neutral.

3. To find the factor of any number x.

4. To calculate the factorial of any number x.

5. To determine x if ax^{2} + bx + c = 0 of any numbers a, b, and c.

6. To compute f(a) of any function f(x) for any number a.

7. To solve f'(a) of any function f(x) where a is any number.

**Bloky Files**

You can download the codes (format in .bloky) by clicking the images above. Then you can import these files into Bloky.
