Guidance to solve Exercise 3 on Page 58 of Math 4 textbook

Problem:
Find two expressions with equal values:
a) 4 x 2145;                                                             d) (2100 + 45) x 4;                                                               
c) 3964 x 4;                                                             e) 10287 x 5;
b) (3 + 2) x 10287;                           ;                                                g) (4 x 2) x (3000 + 964)

Solution Method:
- Step 1: Calculate the values of the expressions, paying attention to parentheses. Evaluate expressions inside and outside the parentheses accordingly.
- Step 2: After calculating the values of the expressions, compare the results and draw conclusions. 

Answers:
a) 4 x 2145 = (2100 + 45) x 4 (= expression d)
c) 3964 x 4 = (4x 2) x (3000 + 964) (= expression g)
e) 10287 x 5 = (3 + 2) x 10287 (= expression b)
