Example of mathematical operations:

Example:

Solve the following equation:

[2 .( 3 + 5) - 5 + 2] x 3 =  ________  

Solution:

a.         Perform operations within the innermost set of parentheses.

3 + 5 = 8

b.         Rewriting the equation:

[2.8 - 5 + 2] x 3 =

c.         Perform multiplication prior to addition & subtraction within the brackets.

[16 - 5 + 2] x 3 =

[11 + 2] x 3 =

[13] x 3 =

d.         Perform multiplication outside the brackets.

13 x 3 = 39

Example:

Solve the subsequent equation:

5 + [2 (3 + 1) - 1] x 2 =          

Solution:

5 + [2 (4) - 1] x 2 =

5 + [8 - 1] x 2 =

5 + [7] x 2 =

5 + 14 = 19

Example:

Solve the following equation:

[(10 - 4) ÷ 3] + [4 x (5 - 3)] =             

Solution:

[(6) ÷ 3] + [4 x (2)] =

[2] + [8] =

2 + 8 = 10
