Number Bonds solves the requirements to practice for mixing different numbers to improve the mental math. The app presents simple to difficult math questions and progresses the levels as as per the user's ability to solve complex problems. The app is bundled with two fun loving math practice activity games. 1. Calculate the Numbers 2. How do we make Numbers Both programs, in a fun to learn activity, silently develops the following abilities • Understanding combination of different numbers produces the same result (2 + 7 = 9 and 5 + 4 = 9). • Left to right, Top to bottom sequence to solve math equations. • Builds ability to solve complex problems. • Understanding about how a set of opposite numbers cancel each other (+5 -5 = 0 & +2 - 2 = 0). • Calculated estimation. • Examination of a product’s construction. (reverse engineering an equation). • Increases the attention span. • Mental arithmetic. • Speed calculations. The app has several salient features. • The app is providing many controls to adjust the generated question to suite various requirements. • The app difficulty level can be made fixed. • Coins, awards and achievements builds motivation to keep practicing. • Drag and drop scenario are meditating for kids and they keep their interest in practicing math. • Randomized, simple yet challenging questions to solve. • The app’s interface is user friendly and attractive. 1) "Calculate the Following" is for relatively young ones. It generates a very simple question and ask the user to drag the correct answer in the Answer Box. It generates a math question that is primarily built for early learners (grade 1). The operation is limited to addition and subtraction only. 2) "How do we make Numbers" is ideal for to any age group. The app generates a math equation where the user has to guess the missing number. Depending on the difficulty level, the operation can involve addition, subtraction, multiplication and division of higher numbers. Also, a question might have two blank pieces to fill. NOTE: The app uses left to right sequence for calculation and doesn’t use DMAS rule for a simple reason (i.e. to improve the speed mental math).
