### Post of the Week

If one loves logical problem then there is great possibility that one will love mathematics. In this post I am putting some easy mathematical puzzles. These puzzles use basic mathematical operation like addition, subtraction, multiplication and division.

These math riddles use BODMAS. So one must know BODMAS before trying to solve these math puzzles. Before posting these quick math riddles, let me give a quick introduction To BODMAS. While simplifying expressions involving brackets we must proceed in order of the letters of the word BODMAS. There are four types of brackets which has to be solved in the order given below.

1. Bar

2. Round bracket ()

3. Curly bracket {}

4. Square bracket []

Order of BODMAS operations is explained in picture below with Left side as highest priority and right side as lowest priority.

These math brain teasers can be used by kids. Teens in higher school will find these math questions very easy. Try not to use calculator while solving these puzzles. It will be more fun to solve these math IQ question in case one try to solve it mentally without using any pen or pencil.

Answer of these basic and quick Math riddles as given as below. I have hidden these answers to avoid anyone looking inadvertently at these answers. To read the answer, do select the text between the numbers to highlight and read the corresponding answer.

45÷ (20-5x3)-3 Of 3. Using BODMAS

= 45 ÷( 20-15)-3of 3

=45÷(5)-9

=9-9=0

A2. 3

12of 3 ÷6x3-5 Of 3.

36÷6x3-15 ( solving of which means multiplication)

= 6x3-15( solving division)

= 18-15=3 ( multiplication and subtraction)

A3. 11.

33 ÷11 Of (5x3-48 ÷4) + 10

33 ÷11 of ( 15-48÷ 4)+10

33÷11 of ( 15- 12)+10

33÷ 11of 3+10

33÷ 33+10

1+10=11

A4. 21.

[25-{5 Of 4 ÷ (10- 5)}]

[25-{20÷(5)}]( solving round bracket and of)

= [25-{4}]( solving curly bracket)

= 21.( solving square bracket)

A5. 2

40÷ [ 20-{10 – 5 Of 2( 7-6 ) }÷10]

=40 ÷[20- {10-10(1)}÷10]

= 40 ÷[20-{10-10}÷10]

=40÷[20-0÷10]

= 40÷[20-0]

= 40 ÷20=2

A6. 24.

2[6 Of {8-(10x 4 -2 Of 5)÷5}]

2[6 of {8-(40-10)÷5}]

=2[6 of {8-30 ÷5}]

= 2 [ 6 of {8-6}]

=2 [6 of 2]

=2[12]= 24.

A7. 1006

10x100+ [600÷{100- (50-5x10)}]

10x100+ [600÷{100- (50-50)}]

=10x100+[600÷{100-0}]

=10x100+[600÷100]

=1000+6=1006

.

A8. -466

564 ÷141-( 10x50)+ 6of 5

564÷141-(500)+30

=4-500+30= 34-500 = -466

A9. 400

20 Of { 6x4-4 Of 3÷(9 X10- 3x 29)}

=20 of {6x4-4of 3 ÷(90-87)}

= 20 of {24-12÷3}

=20 of {24-4}

= 20 of 20= 400

A10. 46.

56-5 Of 30 ÷15

=56- 150 ÷15 (solving of)

=56- 10 (solving division)

=46
