Vedic Multiplication vs Hydraulic ToolKit

Vertically and Crosswise Multiplication helps students learn and practice a compact visual multiplication method step by step. The method is commonly associated with Shri Bharti Krishna Tirthaji’s book “Vedic Mathematics,” published in 1965. In this method, numbers are multiplied using a sequence of vertical and crosswise multiplications. Two-digit multiplication can be completed in three main steps: vertical, crosswise, and vertical. Three-digit multiplication uses five main steps: vertical, crosswise, vertical, crosswise, and vertical. The method has similarities with lattice and grid multiplication. With practice, students may be able to do more of the steps mentally and solve multiplication problems without writing every step down. Features: * Step-by-step vertically and crosswise multiplication practice * Multiplicand can have up to 3 digits * Multiplier can have up to 3 digits * Students can enter their own problems * Current operation for each column can be hidden * Operands for the current operation can be highlighted * Three visual themes * Native interfaces for iPhone and iPad Other iDevBooks Math Apps: Other iDevBooks math apps include Visual Multiplication Table, Decimal Rounding, Whole Number Rounding, Column Subtraction, Column Addition, Long Division, Long Multiplication, Lattice Multiplication, Fraction Math, Partial Differences Subtraction, Partial Quotients Division, Partial Sums Addition, and more.

Designing infrastructure that conveys and stores water relies on sound hydraulic calculations to determine where the flow goes, how deep it is, and how fast it’s moving for safe and efficient operations. From pipes and channels to weirs, orifices, and watersheds, engineers routinely apply hydraulic equations to size components and verify performance. Developed by Wade Trim engineers, the Hydraulic ToolKit app allows users to perform everyday hydraulic calculations anytime, anywhere. While software and spreadsheets are typically used to perform hydraulic calculations, the process often takes place using a computer in the office. This free app is a simple and portable tool to make quick calculations more convenient. Hydraulic coefficients required to perform the calculations can also be referenced. Common uses include verifying a basic hydraulic understanding during a meeting for a school or work project, or checking performance in the field during site observation or startup. Seven hydraulic formulas (Rational Formula, Rectangular Weir Formula, Circular Orifice Flow, Full Circular Pipe Flow, Velocity in a Circular Pipe, Trapezoidal Channel, Rectangular Conduit Full Flow) can be calculated using the imperial or metric system. The Hydraulic ToolKit app is intended for quick and basic calculation checks that do not replace detailed design analyses.
