  • Hi, everybody! Welcome back to Top Words.

  • My name is Alisha and today we're going

  • to be talking about 10 must know math

  • word. So let's go!

  • Plus. The first word is plus, you might

  • have this + sign on your keyboard, you

  • probably do, it means to add something. So

  • like, one plus one equals two.

  • It's an addition related phrase, plus.

  • Minus, the next one, the opposite of plus

  • is the - sign. So in this case,

  • two minus one equals one. So it's a

  • subtraction. That's related to subtraction,

  • taking away something, minus.

  • Times. Ok, the next one is times, we use for

  • multiplication, so it's represented by an

  • x symbol. So 2 times 2 equals 4. We use x.

  • 2 x 2 equals 4, it's a multiplication

  • related word. I wonder why we use x. 2 x 2.

  • Divided. divided as the verb, so

  • 2/2 equals 1, for example. Divided by is that

  • dot line dot symbol. 2/2 equals 1. You

  • can use "divided by", is the expression, two divided by...

  • Equal. Equal or equals, we use this before

  • we present the solution to a math

  • problem, so 2 times 2 equals, with an s,

  • equals, it equals four,

  • for example. You can also use equal to

  • show that two things have the same value,

  • two is equal to two. This value is equal to

  • that value, that's another way that you

  • can use the word equal. Equation, the next

  • math word is equation. Equation, so up

  • until now we've been talking about a

  • part of an equation but the whole math

  • problem everything there is called the

  • equation, so the process that you need to

  • do in order to solve an equation. An

  • equation is something that you do to

  • solve a problem. This this part of the

  • equation, this part is the solution.

  • The ending the result is the solution.

  • The problem is called the equation, the

  • process, the math process to find a solution.

  • Percent. Percent, this is a very useful word you

  • can use, of course, when doing math or

  • maths problems, but you can also use this

  • when shopping, for example. So a sale is

  • five percent off, ten percent off, it

  • represents a discount.

  • You can also use percent to describe

  • effort levels, for example, a sports team

  • coach might tell his team,

  • I need you to work at a hundred percent

  • today. So it's used to express the

  • level of something, but it can also be

  • used in sales and in math related terms.

  • Remainder. The next word is remainder.

  • Remainder is used when doing a division,

  • it means, remainder means

  • something that is left over. So when

  • doing division, when doing division

  • problems, sometimes there's a

  • problem or an equation that results in

  • a number that is not round, or a

  • number that is not whole. So for example,

  • 1.2 might be a solution to a math

  • problem, the 0.2, that is the

  • remainder there, that's what's left over.

  • So it's not a whole number but there's

  • something, a little bit, that's left,

  • that's remaining, that's called the

  • remainder, something that's left over.

  • Even. The word even represents numbers

  • like two four six eight ten twelve, we

  • consider those numbers even, they end in a

  • 2, 4, 6, 8, or 0, those are the even numbers.

  • Odd. So the next word is odd, which

  • represents the numbers that are not even.

  • 1, 3, 5, 7, and 9, any number that ends in

  • one, three, five, seven, or nine is called

  • an odd number. Anything that ends in two,

  • four, six, eight, or zero is an even number.

  • Alright, so those are 10 math related

  • words that are actually quite useful, you

  • can use them to talk about, of course,

  • math equations, but they're also useful in,

  • perhaps, in some business situations and

  • when shopping. So give them a try. Thanks

  • very much for watching this episode of

  • Top Words, and we will see you again soon. Bye!
