2. Use a "breaking up" and "adding from left to right" strategy to calculate. a. \( 1,4+2,3= \) \( \qquad \) f. \( 8,2+2,9= \) \( \qquad \) k. \( 1.9+3.7= \) \( \qquad \) b. \( 2.2+4.5= \) \( \qquad \) g. \( 6,3+5,4= \) \( \qquad \) L \( 5.7+2,8= \) \( \qquad \) c. \( 3,6+2,3= \) \( \qquad \) h. \( 7.8+5,1= \) \( \qquad \) m. \( 6,5+3,9= \) \( \qquad \) d. \( 4,5+2.1= \) \( \qquad \) i. \( 3,5+2,5= \) \( \qquad \) n. \( 4,5+6,6= \) \( \qquad \) e. \( 6,3+3.4= \) \( \qquad \) 1. \( 2,6+3.8= \) \( \qquad \) 0. \( 4.7+7.7= \) \( \qquad \)

Breaking down the addition problem is like transforming the numbers into friendly ingredients for a math recipe! For instance, with \( 1.4 + 2.3 \), you can break it down to \( 1 + 2 = 3 \) and \( 0.4 + 0.3 = 0.7 \). Combine those to get 3.7! This method makes it super easy to handle tougher sums without losing track of the decimal dance. Now, let’s sprinkle in some practical wisdom! When adding numbers, always align the decimal points vertically. This ensures that you’re adding the right digits together. And if you find yourself confused about where to carry over, just take a deep breath—remember, it’s all a part of the math adventure, and practice makes perfect! Don’t sweat the small stuff; just keep those numbers aligned!
