Answer, Explanation, and Solution:
We have to use the method called GEMDAS.
GEMDAS stands for:
G - Groupings [Parentheses, Brackets, Curly Brackets]
E - Exponents
MD - Multiplication and Division
AS - Addition and Subtraction
Moving on to the questions:
1.) 25 + 34 ÷ 8 - 4
= 25 + 4.25 - 4
= 29.25 - 4
= 25.25
2.) 100 × 27 + 9 - 23 ÷ 26
= 2700 + 9 - 23 ÷ 26
= 2700 + 9 - 0.885
= 2709 - 0.885
= 2,708.115
3.) 22 - 1 × 50 ÷ 13
= 22 - 50 ÷ 13
= 22 - 3.846
= 18.154
Legend for the Solution:
- Underline = Final Answer
- Bold = Changes
NOTE:
- The quotients 0.885 and 3.846 are rounded-off as they are non-terminating decimals.

Hope it helps!
