Hi please could you answer the basic math question for question number 4 3. Make-1 in SEVEN different ways by adding different combinations of the numbersbelow. For each set, you may use each number only once...-10-8-7-5 -4 -3 -1 2 3 6 7 9 10 12For the first two sets, you may use only 2 of the numbers (but you can use more); for sets3 and 4, you must use at least three numbers; for sets 5 and 6 you must use at least fourof the numbers; and for the seventh set, you must use at least five of them.4. InvestigationUsing the digits 0-9 (and using each digit only once in each calculation),create subtractions with the answer -9,For example, using combinations of 1 and 2-digit numbers,0-9 = -9;3-12 = -9;39-48-9- using 2/3-digit numbers, 98-107 = -9using 3/4-digit numbers?Try to create as many subtractions as possible with this answer. Can youfind them all, being systematic?TIP: You may like to make the cards 0-9 to help you with this activity.-
