This study is done to determine the best method to teach mathematics and boost the sc1596-JMSSientific level of pupils in basic schools. The pupils’ contributions in grouping make the lesson easier and more enjoyable among them. The identified problem is teaching pupils in the group method and its goal is to improve the group method in teachers' views. The method is descriptive and data analysis. Our objective is to clarify the effectiveness of grouping among pupils in the first circle in basic schools because in teaching mathematics using the grouping method helps pupils understand the subject better. To illustrate, the findings not only facilitate the further understanding of grouping strategy but also provide the teachers with a useful teaching method and a clue that they should use while teaching because each teacher, who participated in the questionnaire compared to their previous experience, believes that the best way to teach mathematics is grouping method.","PeriodicalId":41981,"journal":{"name":"Jordan Journal of Mathematics and Statistics","volume":"18 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83697307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some recent works on fractional differential equations involving Riemann Liouville and Caputo-type fractional derivatives are studied using nonlinear analysis methods such as Krasnoselskii fixed-point Theorems (Agarwal and O'Regan, 1998; Ghanmi and Horrigue, 2018; Guo et al., 2007; Guo et al., 2008), Leray-Schauder alternative (Ghanmi and Horrigue, 2019; Qi et al., 2017), sub-solution and super-solution methods (Wang et al., 2019; Mâagli et al., 2015) and iterative techniques (Liu et al., 2013). Hadamard (1892) introduced an important fractional derivative, which differs from the above-mentioned ones because its definition involves logarithmic function of arbitrary exponent and named as Hadamard derivative. In the last few decades many authors are paying more and more attention to fractional differential equation involving Hadamard derivative, the study of the topic is still in its primary stage. For details and recent developments on Hadamard fractional differential equations, see (Huang and Liu, 2018; Wang et al., 2018; Zhai et al., 2018) and references therein. Recently, some researches have extensively interested in the study of the fractional differential equations with p-Laplacian operators see for examples (Chamekh et al., 2018; Ding et al., 2015). From the above review of the literature concerning fractional differential equations, most of the authors investigated only the existence of solutions or positive solutions for Hadamard fractional differential equations without considering the pi-Laplacian operator. A very few authors established results along with p-Laplacian operator, us example in (Wang and Wang, 2016), the authors considered the following nonlinear Hadamard fractional differential problem:","PeriodicalId":41981,"journal":{"name":"Jordan Journal of Mathematics and Statistics","volume":"139 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86620389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Multiple Linear Regression (MLR) technique and feed forward Neural Network (NN) are used to predict the performance of 11 banks in Botswana. Return on Assets (RoA) is used as the dependent variable, while management quality, credit risk, liquidity, financial leverage and capital adequacy are used as the independent variables. The data is sourced from the financial reports for the year range 2015-2019. When using MLR, the cost-to-income (C_I) ratio (management quality measure) and the loan loss provision to total loans (LLP_TL) ratio (credit risk measure) are found to be the two most significant drivers of bank performance. The NN has an R value of 84.37% which is significantly higher than the R value of 70.00% for the MLR. The cost-to income ratio is found to be the most important driver of the NN. The performance of the two methods (MLR and NN) is then assessed using the Mean Absolute Error (MAE) and Mean Square Error (MSE) as the performance indicators. When using the validation sample, it was found out that the MLR has a MAE of 0.00611 while the NN has a MAE of 0.00472. The MLR has a MSE of 0.00008 in comparison to the NN with a lower MSE of 0.00004. It was then concluded that the NN has better predictive abilities than the MLR.","PeriodicalId":41981,"journal":{"name":"Jordan Journal of Mathematics and Statistics","volume":"25 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82479355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
