Using Electronic Calculators focuses on building competence using desk and
pocket calculators or the numeric keypad on your personal computer keyboard. The text
includes extensive practice with the memory feature common in electronic calculators.
Using Electronic Calculators includes the following features:
- Learn-by-Doing Instruction. Students use a calculator or computer keypad as they
complete the instruction section for each unit. Examples and illustrations guide students
and provide hands-on learning experience.
- Skill-Building Practice. Students practice new operations in the Developing Skill
section for each unit. Answers are provided at the bottom of the page for student's to
check their own progress.
- Applications Worksheets. Students apply their skills as they complete the
realistic exercises in the two-page worksheet that follows each instructional and practice
section.
- Realistic Office Projects. Students use calculating skills to complete business
forms and records in five realistic Office Projects.
- Supplementary Practice. In the back of the book, the Supplementary Practice
section offers extra skill-building exercises for each unit.
For easy grading of Worksheets and Office Projects, a free Instructor's Key is provided
upon request with each class-size order.
