to divide by only using subtraction you just continuously take away until it reaches a number that will no longer allow the number to be taken away and count the amount of times you took away that number
Yes, ancient Romans had methods of multiplication and division using Roman numerals. Multiplication involved repeated addition and division used a method called "long division." However, these methods were more cumbersome and time-consuming compared to the modern decimal system.
Subtractive - because they remove material from the object being ground.
Subtractive. He chiseled marble rocks.
Printing is a subtractive process; all the colors combine to form black.
Is this a trick homework question? I don't believe there is a 100% truthful answer because a subtractive colour is made up of two primaries, and a primary colour is not subtractive any more than a subtractive colour is primary ("...primary subtractive colour..."). Neither can there be a "main" subtractive colour if we are to consider your use of the word "primary" in your question to mean that. The complementary colour to red is cyan, which is made up of blue and green in equal amounts.

Additive sculpture involves building up a form by adding material, such as clay, wax, or metal, to create the final piece. In contrast, subtractive sculpture involves removing material from a solid block, such as stone or wood, to carve out the desired shape. While additive techniques allow for more flexibility and experimentation, subtractive methods often require precision and skill to achieve the desired result. Both approaches offer unique artistic expressions and challenges in the sculpting process.

Light can be both additive and subtractive, depending on the context. In additive color mixing, different colors of light are combined to create new colors, while in subtractive color mixing, colors are created by removing certain wavelengths of light.
There are several methods of division, including long division, which involves breaking down the division process into manageable steps; short division, which simplifies the process for smaller numbers; and synthetic division, commonly used for dividing polynomials. Another method is using repeated subtraction, where the divisor is repeatedly subtracted from the dividend until what remains is less than the divisor. Additionally, the division can be visualized with arrays or using a number line for conceptual understanding.
