Expressions can be all the operations including multiplication, exponents, roots, etc. but including the "verb" of the sentence, the relationship sign like equals.
Arithmetic operators
numbers with Like signs : result Plusnumbers with Unlike signs : result Minus
multiplication signs: x , * , . , (Dot)
no algebraic expressions do not have equal signs but equations do.
They are called operators because they operate all of the operators. Hope I helped!
It looks like a damath board but division and multiplication signs are not used inthis board.
If you're talking about multiplication or division, then opposite signs will result in a negative number.
The rules for division are exactly the same as the rules for multiplication. * Division (or multiplication) of a positive number by a positive number = positive * Division of a positive number by a negative number = negative * Division of a negative number by a positive number = negative * Division of a negative number by a negative number = positive If you have trouble remembering any of these, just try out a sample division on any calculator - for instance, if you divide (-1) / (-1) you get +1.
Expressions never have equality signs
The answer depends on which binary operation you mean when you say "combining". Addition, subtraction, multiplication, division, exponentiation, etc.
Robert Recorde, who designed the equals sign, introduced plus and minus in 1557. Brahmagupta was an Indian mathematician who invented the multiplication sign around the 19th century. Johann Rahn first used the division sign in his book Teutshe algebra in 1659.
