100 * 10 - 100+2000 / 100 =?
$$100 \times 10 - 100+ \frac{2000}{100} =?$$
Correct Answer: C [920]
Explanation:
\(100 \times 10 - 100+ \frac{2000}{100} =?\)
According to BODMAS Rule,
\(100 \times 10 - 100+ 20 =?\)
\(1000 - 100+ 20 =?\)
\(1000 - 120 =?\)
= 920
Note:
BODMAS Rule is
Step 1: Parts of the expression enclosed in ‘Brackets’ must be solved first. Inside the brackets, once again BODMAS rules apply! Just like a Russian Doll!
Step 2: The mathematical operators ‘of’ and ‘order’ must be solved next. ‘Of’ means part of and is solved by substituting with a multiplication sign. ‘Order’ is the same as exponent. Powers are solved after brackets. Powers also include roots.
Step 3: Next, the parts of the equation that contain ‘Division’ and ‘Multiplication’ are calculated.
Step 4: Last but not least, the parts of the equation that contain ‘Addition’ and ‘Subtraction’ should be calculated.
