<p>The Analytical Engine had 1000 words of 50 decimal digits each for variables or results, and it could accept values from the store to add, subtract, multiply, or divide them before returning the result to the store. It also could read instructions from punched cards and had instructions for various operations such as fetching values, adding them, and conditionally branching based on the number's positivity or negativity.</p> Signup and view all the answers
