Hint: Follow the BODMAS rule. BODMAS stands for “Bracket Of Division Multiplication Addition Subtraction”.

Complete step by step solution:
To solve any simplification always follow the BODMAS rule. It means “Bracket Of Division Multiplication Addition Subtraction”, that is the operations mentioned should be carried out in the stated order. So first the brackets need to be simplified then the division needs to be carried out then multiplication followed by addition and then subtraction.
In this case the question is \[10 + 8 \div 2 - 4\]. Here there is no bracket so next, we check for the division operation.
So first carry out the division:
\[10 + 8 \div 2 - 4\] \[ = 10 + 4 - 4\]
Next complete the addition:
\[ = 14 - 2\]
Finally the subtraction:
\[12\]

Therefore the simplified form of \[10 + 8 \div 2 - 4\] is \[12\].

Note:
In certain regions, BODMAS Is also known as PEDMAS rule which stands for. “Parenthesis Exponents Division Multiplication Addition Subtraction”. Both BODMAS and PEDMAS rule helps by an acronym to remember the proper order of mathematical operations to solve problems. Also for the brackets, if the first bracket “()”, the second bracket “{}” and third bracket “[]” are present, first the first bracket is solved then the second and finally the third.
