Solution:
To solve the expression, 25 - 4 x (7 + 5) ÷ 4 + 3 we need to follow the order of operations, also known as BODMAS (Brackets, Order, Multiplication, Division, Addition, and Subtraction).
25 - 4 x (7 + 5) ÷ 4 + 3
= 25 - 4 x (7 + 5) ÷ 4 + 3 ----> Brackets
= 25 - 4 x 12 ÷ 4 + 3 ----> Multiplication
= 25 - 48 ÷ 4 + 3 ----> Division
= 25 - 12 + 3 ----> Subtraction
= 13 + 3 ----> Addition
= 16
