The research aims to know what the creative thinking mathematically significant effect against the ability of solving math problems. Methode in this research is a quantitative approach wiht the correlation. Paradigms of research used in the form of paradigma single, 2 (two) variables, the location of Selected by Probability Random Sampling which had previously been done pengan test validity and reliability of the instrument. The main of instrumen essay from the data is collected, then analyzed with testing statistics and continued with the hypothesis testing with simple linear regression test. With the requirements of analysis in the form of normality test and linearity test, Based on a simple linear regression test of mathematical creative thinking to the ability of solving mathematical problems of research results showed that.The F value in the Deviation of Linearity column is 3.850 and the significance is 0.05 (5%), the Sig (2-tailed) value is 0, 076, Thus, the Sig. (2-tailed value is less than the significance value of the Sig. (2-tailed) value of 0, 076 so it can be concluded that the relationship of creative thinking with the ability to solve mathematical problems is linear.
