This document discusses how to solve multi-operational word problems that involve more than one math operation. It recommends carefully reading and understanding the problem, and optionally drawing the problem to identify the necessary operations and equation. The ESA Method is introduced as a way to solve these problems, which stands for: E (Express the question in an equation), S (Solve the equation), and A (Answer the question). Three sample word problems are presented and solved using the ESA Method to illustrate this process.

MULTI-OPERATIONAL WORD PROBLEMS Multi-operational word problems are word problems that involve MORE THAN ONE OPERATION.
HOW TO SOLVE? In solving Multi-operational Word Problems, the key is to READ and UNDERSTAND the problem carefully. You MAY ALSO DRAW the problem. That will help a lot especially when finding out the operations necessary, and formulating the equation needed to solve the problem. ESA Method is also used in solving these
LETS TRY! At sir Romes house, there are 2 chicken, 3 dogs, and 5 cats. What is the total number of legs of those animals at sir Romes house?
ESA METHOD E: 2 2 + 3 4 + (5 4) = S: A: 36 legs
LETS TRY! Kara bought 2 pieces of ribbon for 75 pesos each, 5 pieces of shirt for 258 pesos each, and 7 skirts for 150 pesos each. If she had 5,000 pesos, how much would be left for her?
ESA METHOD E: 5,000 2 75 + 5 258 + (7 150) = S: A: 2,510 pesos
LETS TRY! In the first quarter, Joshua was able to collect the following Reci-balls: 12 Pok辿balls (1 pt), 6 Great Balls (2 pts), 4 Ultra Balls (3 pts), and 3 Master Balls (5 pts). What is the total recitation points he had collected for that quarter?
