Solve Exercise 3 on Page 102 of Math Textbook Grade 3
Problem: Calculate the value of the expression.
Solution Guide: - For expressions involving multiplication, division, addition, and subtraction, perform multiplication and division first, then addition and subtraction. - For expressions with parentheses, perform operations inside the parentheses first. - For expressions containing only multiplication, division, addition, or subtraction, proceed from left to right.
The solutions are as follows: a) 7,479 + (3,204 × 5) = 7,479 + 16,020 = 23,499 b) (24,516 - 4,107) ÷ 3 = 20,409 ÷ 3 = 6,803 c) 14,738 + 460 + 3,240 = 15,198 + 3,240 = 18,438 d) 9,015 × 3 × 2 = 27,045 × 2 = 54,090
