Across 6. a process. the way you do the maths. eg: 5b+6 8-6 10ax7 9. the symbols to groups things together eg: (2a+b) 4 - 2c= 11. a number imultiplied by itself Example: 4 × 4 = 16. 4 is a _____. 12. symbols for plus, multiply, minus, divide etc 13. the numbers on their own for example 2a + 4. 4 is by itself. 14. a special type of equation where the symbols have a relationship eg: volume= LWH

Down 1. the part of maths where letters and symbols represent numbers 2. In this example, −2 and 2 are the roots of the function y=x − 4 3. a symbol for a number we don't know yet. for example 2a+3=? A is a variable 4. a number used to multiply a variable: for example 2a 5. numbers and letters that are equal. for example a+6=10 7. this says how many times to multiply. for example 8 8. the same, so they can be added together eg: 2y+3y =5y. bu not 2x+5y=7xy 10. when a letter represents a number 10-3=a. we know that a=7.
