tract the relevant information from the problem text. Our method learns to map arithmetic word problem text to math expressions, by learning to select the relevant declarative knowledge for each operation of the solution expression. Find the last digit of 7100 [Solution: 1] 7100 (72) 50 49 ( 1)50 1 mod 10. stream In this article, we, Math word problems form a natural abstraction to a range of quantitative reasoning problems, such as understanding financial news, sports results, and casualties of war. We develop a theory for expression trees that can be used to represent and evaluate the target arithmetic expressions; we use it to uniquely decompose the target arithmetic problem to multiple classification problems; we then compose an expression tree, combining these with world knowledge through a constrained inference framework. Solution: a) For -3.4, we split the number line between the integers -4 and -3 into one ten equal pieces and then count to the left (for negatives) 4 units since the digit 4 … This sat-, For the inductive case, we assume that for all expres-, we need to prove that any expression with, Consider a valid (as in all cases) expression, 3.2, we know that the chains containing the roots of, containing the root, or both belong to one of the chain, operation will be identical. Arithmetic starts right away in the Pre-k to other higher grades that is the 6th and the 7th grade.

This is, to our knowledge, the first learning result for this task. lems, for which all quantities were correctly classiﬁed. Commonly used models typically ignore expressive dependencies since the traditional way of incorporating non-local dependencies is inefficient and hence leads to expensive training and inference.

Our experiments on six benchmark domains show that a small amount of search in limited discrepancy search space is often sufficient for significantly improving on state-of-the-art structured-prediction performance.
