Simple Arithmetics



Now it’s simple to teach math with the brilliant methods that Charlotte Mason used with her students. These short, interactive, and lively lessons will take you and your child on an enjoyable journey through the mountainous land of the Principality of Mathematics, where “you cannot lose your way, and every step taken is on firm ground” (Ourselves, Book 1, p. Arithmetic definition is - a branch of mathematics that deals usually with the nonnegative real numbers including sometimes the transfinite cardinals and with the application of the operations of addition, subtraction, multiplication, and division to them. How to use arithmetic in a sentence.

ARITH - Simple Arithmetics


One part of the new WAP portal is also a calculator computing expressions with very long numbers. To make the output look better, the result is formated the same way as is it usually used with manual calculations.

Your task is to write the core part of this calculator. Given two numbers and the requested operation, you are to compute the result and print it in the form specified below. With addition and subtraction, the numbers are written below each other. Multiplication is a little bit more complex: first of all, we make a partial result for every digit of one of the numbers, and then sum the results together.

Input

Simple arithmetic pdfSimple

There is a single positive integer T on the first line of input (equal to about 1000). It stands for the number of expressions to follow. Each expression consists of a single line containing a positive integer number, an operator (one of +, - and *) and the second positive integer number. Every number has at most 500 digits. There are no spaces on the line. If the operation is subtraction, the second number is always lower than the first one. No number will begin with zero.

Output

For each expression, print two lines with two given numbers, the second number below the first one, last digits (representing unities) must be aligned in the same column. Put the operator right in front of the first digit of the second number. After the second number, there must be a horizontal line made of dashes (-).

For each addition or subtraction, put the result right below the horizontal line, with last digit aligned to the last digit of both operands.

For each multiplication, multiply the first number by each digit of the second number. Put the partial results one below the other, starting with the product of the last digit of the second number. Each partial result should be aligned with the corresponding digit. That means the last digit of the partial product must be in the same column as the digit of the second number. No product may begin with any additional zeros. If a particular digit is zero, the product has exactly one digit -- zero. If the second number has more than one digit, print another horizontal line under the partial results, and then print the sum of them.

There must be minimal number of spaces on the beginning of lines, with respect to other constraints. The horizontal line is always as long as necessary to reach the left and right end of both numbers (and operators) directly below and above it. That means it begins in the same column where the leftmost digit or operator of that two lines (one below and one above) is. It ends in the column where is the rightmost digit of that two numbers. The line can be neither longer nor shorter than specified.

Print one blank line after each test case, including the last one.

A basic arithmetic test will challenge your skills and knowledge of the most basic mathematics. Due to the purpose of the test, calculators are never allowed for these tests, although using pen and paper is recommended.
What questions can I expect?
In a basic arithmetic test you are required to solve simple mathematical equations and answer questions regarding basic mathematics. When facing a basic arithmetic test, we suggest that you brush up on the following topics:

  • Order of Operation
  • Fractions
  • Decimals
  • Percentages
  • Square roots
  • Powers and exponents
  • Conversions
  • Measurement, including money, distance, area, and volume

In addition to these topics, we suggest that you practice your mental calculation of addition, subtraction, multiplication, and division. Being able to make fast and accurate calculations mentally will improve your performance significantly. With our Test Prep Account you will get access to our Math Knowledge Study Tool, which will help in your preparation, as well as our practice questions.Basic arithmetic problems
Where are Basic Arithmetic tests used?
These tests are frequently used as pre-employment assessments for occupations requiring basic mathematical skills. These occupations include: clerks, cashiers, receptionists, teachers, and more.
