# Addition or Subtraction Sign Worksheets

What Does an Addition or Subtraction Sign Mean? Even though math is quite a confusing and tricky subject, there are many things that the subject has simplified for us. Yes, yes, it uses a lot of symbols and variables, but each of these symbols and variables has a much simpler meaning, and you can know what it means by paying a little concentration and close attention. We all know that when we use the word "yes," it means that we are agreeing to something, and when we use the word "no," we are giving a negative response to something. Similar to that, math, too, has a list of words, signs and symbols that have a meaning to them. If you see a + sign in the given question, it means that you are required the total sum of all the numbers that are given to you. This is known as addition, and the symbol is known as the plus sign. If the question has a - sign, then it means that you are supposed to find the value by taking out the lesser value from the bigger value. The method is known as subtraction, and the sign is known as the minus sign.

• ### How to Determine If an Equation is Missing an Operation

One of the most difficult parts about math is probably the word problems, isnâ€™t that right? Word problems have many things that you need to figure out and arrange before you can jump into solving them. Just like that, sometimes, there are equations that are missing a digit or even an operation. So, if you are in need of help to identify whether the equation is missing an operation or not, you have come to the right place! Let's take a look! First things first, always remember, that an equation is known as an equation because it has the equals sign. It is divided into two sides, and in the middle of the two sides, there will always be an equal sign. The next thing you need to remember is that if the numbers in the equation are increasing, you need to use the addition or multiplication symbol, but if the numbers are decreasing, the symbols used will be division or subtraction. The only thing left to do is to test! And you are done!

Add up all the numbers on the keypad of your phone. Multiply that sum by the all the numbers on the keypad of your phone. But you have to do it without looking at your phone! See if you can do it in less than the average time of 30 seconds.
