Answer:
197 - [19{42 + (56 - 8 + 9)} + 108] = (-1792)
Step-by-step explanation:
We have,
197 - [19{42 + (56 - 8 + 9)} + 108]
Now, to solve these kinds of Questions, we must follow the famous mathematical BODMAS rule/order.
B¹ - Bracket
O² - Of
D³ - Division
M⁴ - Multiplication
A⁵ - Addition
S⁶ - Subtraction
This is the order we must use to solve this Question.
197 - [19{42 + (56 - 8 + 9)} + 108]
So, we solve the 1st simple bracket, we first add the terms then subtract it according to BODMAS.
= 197 - [19{42 + (56 + 9 - 8)} + 108]
= 197 - [19{42 + (65 - 8)} + 108]
= 197 - [19{42 + (57)} + 108]
= 197 - [19{42 + 57} + 108]
= 197 - [19{99} + 108]
= 197 - [19 × 99 + 108]
Putting just brackets simply means multiplication.
Now, in the BODMAS order multiplication comes first
So,
= 197 - [1881 + 108]
= 197 - [1989]
= 197 - 1989
Now, you might feel we went wrong somewhere, but we didn't, when we have to subtract a bigger number from a smaller number, it becomes negative.
How, to solve this is, we just subtract normally, that is, we subtract 197 from 1989 and then add a negative sign to the answer.
= (-1792)
Thus,
197 - [19{42 + (56 - 8 + 9)} + 108] = (-1792)
Hope it helped and believing you understood it........All the best
